The intel !igent computer-
controlled droid on this
issue's cover was designed
on the Cover: and drawn by Debbie Woods,
an artist from San Jose,
California.
I recently returned from a
trip to California. Sinclair con-
puting is alive and well in that
large west coast state, and I was
able to visit with some interesting
T/S enthusiasts (in-person and a
few on the phone). Jerry Chamkif,
president of Aerco im Austin, Texas
was also in California on business
(and vacation) at the same time as
I was, but unfortunately our paths
never crossed. Jerry demonstrated
his new 2068 Disc System at the
San Francisco Users Group meeting.
There were some problems with the
disk software and the system
crashed a few times. This has been
corrected with some help from Jack
Dohany of Menlo Park, CA. Aerco
started shipping Disc Systems and
Interfaces: on- Apri 72.
My first stop was Sunset Elec-
tronics down by the waterfront in
San Francisco, to meet with owner
and proprietor John Warburton. This
1s one of the few.adctual stores in
the U.S. that deal in Timex Computer
Equipment and Accessories. I even
found Time Designs Magazine on the
book rack there. Sunset Electronics
also does a large mail order business
(32 page catalog available upon re-
quest. Writs to: -2254 Tereyal Sires
San Francisco, CA, 94116). John end
some other T/S users in the Bay Area
were preparing for the annual West
Coast Computer Faire on March 30-
April 2. Arrangements had been made
with Sinclair to show a QL there.
Down the Peninsula a few miles,
in the Silicon Valley I found the
manufacturing and operating facility
of A & J Micro Drive. Jim Howell is
the ''man-in-charge" here, and they
have recently introduced a stringy-
floppy system for the -stock T/S 2068.
Along with Jim, there are 10 other
employees who assemble and test the
drives and wafers. A & J's biggest
business is drives and interfaces
for various models of electronic
—\ Editors Corner
typewriters on the market. While I
was. there, Jim told me that he had
purchased the rights and equipment
of the wafer technology used in the
T/S 1000 Micro Drive from Entrepo
(the inventors). A § J will now
incorporate the model 1000 Style
wafers (version 0) and drives into
the model 2000 for the T/S 2068.
The original model 2000 used a
different wafer (version 2) and are
not compatible with the new units
being shipped. On the outside the
model 2000 Micro Drive will remain
the same.
Before heading south, I chatted
on the phone with Bob Orrfelt of
Redwood City, CA and also Rita Cary .
who is the chairperson of the Silicon
Valley T/S Users Group. Bob Orrfelt
has his own cottage industry and
offers a 64 Col. Word Processor for
the 2068, and some nifty new EPROM
Cartridge Boards. Among some other
things he has been working on is
fixing up the "bugs" in the 2068's
ROM. Bob may be contributing some
information for Time Designs readers
in an upcoming issue.
Down in Los Angeles, home of
congested freeways, smog and Mickey
Mouse...I met with Sinclair computer
expert. Dave Clifford. Dave:wrote a
review in our last issue on the Z-
Link interface card. He is also very
knowledgeable on telecommunications
using the Westridge 2050 Modem and
MTERM II Software. Dave demonsrated
his Sinclair Microdrives on the 2068
for me. They are very compact little
units, but also very fast!
Well here we are back "home".
And before closing, I want to say
thank you to all of you who have
mentioned or shown your copy of Time
Designs to other T/S users. It is
appreciated and benefits us all. Not
only does it increase our circulation,
but it will also enable us to add
more pages and articles to the mag-
azine for you.
See you next issue!

letters to the editor
Dear Tim,
Yesterday, as one of the guest
speakers at the bi-monthly meeting
of the West Los Angeles ZX81 Users
Group, I received a complimentary
copy of the March/April '85 issue
of Time Designs through the co-
operation of Ed Gray.
What a nice job you're doing!
I found your magazine contained
lots of useful material, was clearly
printed, and reasonably free of
typos. The reproduction of LISTings,
photos and graphics was particularly
good compared to most other Timex/
Sinclair publications (mostly news-
letters).
My personal involvement in the
Sinclair/Timex world has been min-
imal since I completed my Howard
W. Sams book on the 2068 almost
two years ago ("'TIMEX SINCLAIR 2068
BEGINNER/INTERMEDIATE GUIDE"). I've
Since written three other books-
the "awful" ADAM, the "spectacular"
Sanyo MBC 550 Series, and the "rot-
ten" Apple //c. (Those quotes rep-
resent my one-word reaction to the
computer.
However, your readers might
be interested that last December
I got the loan of an English Sin-
clair QL for a month, and did an
over-7000 word detailed review for
MODERN ELECTRONICS (76 North Broad-
way, Hicksville, NY 11801, $12.97
for 12 monthly issues). This slick
new magazine (8 issues so far) is
about 100 pages per issue, and
covers the whole field of electronics
for hobbyists and experimenters, with
considerable computer coverage. They
have scheduled the QL as the cover
story of the June issue, which comes
out in May, pending FCC approval of
the U.S. QL (which is expected anv

SINCLAIR NEWS
Sinclair of the U.K. has just recently
returned from a couple of electronics in-
dustry trade shows in the Soviet Union.
The Kremlin is trying to upgrade their
culture and education system with micro-
computers similar to what one might see in
a typical American elementary school class-
room. The iron curtain hi-tech industry is
years behind other parts of the world as far
as mass production. Existing microcomputers
in the Soviet Union consist of poor copies
of the Apple II. Sinclair demonstrated their
Spectrum Plus and QL to the eager Soviets.
I wonder what they thought of “one stroke
keyword commands?"
Sinclair has ceased production of the
original ZX Spectrum (16k and 48k versions),
and is marketing exclusively the Spectrum
Plus. This computer is styled after their
top-of-the-line QL. Has an improved keyboard
and 48k RAM.
Speaking of the QL, Mary Reinman of
Sinclair (U.S.) could not give us word of
it's release as we went to press. The comment
was made that FCC approval was just "a couple
of weeks" away. Some experts here and abroad,
claim that FCC has already approved the com-
puter, and that Sinclair is waiting for
units to ship before they announce avail-
ability.
One U.S. vendor that is patiently
waiting for the release of the QL, is Curry
Computer (5344 W. Banff, Glendale, AZ 85306).
They have stocked a large quantity of QL
software and books. They also publish a news-
letter called "The QL Report". In the April
'85 issue that we received, there was a
sample of a QL screen display from a program
called "GRAPHIQL". Very impressive.
The English computer press has not
always been very kind towards the QL, and
on more than one occasion remarked about
it's rather "slow" operating system. How-
ever, the few individuals here in the U.S.
that are fortunate to own the British QL,
are very pleased with the computer and speak
very favorably of it. We have yet to see
what changes Sinclair made on the machine
to bring it to America.

TELECOMMUNICATIONS
The Weymil Corp. (Box 5904, Bellingham,
WA 98227-5904) has a software package called
MINI XMOD 1.5 for the ZX81/TS 1000/1500 and
the Westridge and Byte Back modems. It has
the ability to access the CPM files section
of any XMODEM protocol BBS to up or download
Timex programs. Features include memory
storage of screen displays and an indicator
that reports when memory is full. Document-
ation and step by step instructions is in-
cluded. There are both 16/64k versions. The
64k version stores easily in the Hunter
Board for instant recall. Price is $20.

OLIGER/KINGSLEY DISC SYSTEM
In a joint venture between John Oliger
and Ray Kingsley (of Sinware), a new in-
expensive disc drive controller for the
2068 will be available sometime in mid
June. The hardware for the disc operating
system is being designed by John Oliger,
while the software to boot up the controller
is being programmed by Ray Kingsley. The
main disc interface board is already com-
pleted. It will support up to four single
or double sided, single, double or quad
density 3 to 5% inch drives. The data
transfer rate of this board (5;-double
density) is 32k bytes per second...the
actual rate will be determined by the soft-
ware efficiency. Software support is only
planned for the 2068, and possibly the
Spectrum (in the future).
Further hardware for the controller
include a firmware/bank logic/memory board
and/or the 64k memory/CPM board. These two
boards are furthest away from production,
but should be coming along soon. It is hoped
that the system will respond like the Sinclair
Interface One with Microdrives, and use all
the BASIC supported keywords (including
SAVE and LOAD). Prices on the boards are
still to be determined. It should also be
pointed out that the controller is designed
for use with the Oliger 2068 Expansion
Board.
Specific comments/suggestions con-
cerning hardware for the system should be
addressed to: The John Oliger Co., 11601
Whidbey Dr., Cumberland, IN 46229. Comments,
suggestions, ect. regarding software should
be addressed to: Ray Kingsley, C/O Sinware
Software, P.O. Box 8032, Santa Fe, NM 87504.
If you would like to be put on the system's
“inform when ready" list, drop John a post-
card.
Mr. Oliger also announced availability
of his new 2068 Parallel Printer Port. It
is a Centronics type and comes complete with
software on cassette. It is also Aerco
compatible as far as commercial software
is concerned. It is perhaps the lowest
priced printer interface of it's kind, with
the fully assembled and tested version (with
cable) going for $47.90. The kit with parts
is $24.95 (add $16.95 for cable), and a bare
board is available for $16.95 and includes
the cassette. A 15 page user manual is
supplied with every version.

MISC.
E. Arthur Brown has always put out a
very professional and slick brochure. The
most recent one continues the tradition.
It probably has something to do with Eben
Brown's (the owner) experience in the pub-
lishing business. The EB7 catalog is on
newsprint paper and features a host of hard-
ware and software for Timex computers. For
your copy, write to: 3404 Pawnee Dr., Alex-
andria, MN 56308.
The printer interface cable and soft-
ware for the A & J Model 2000 Micro Drive
is now available. For information and price
write to: A & J Micro Drive, Suite I, 1050
E. Duane Ave., Sunnyvale, CA 94086.
The address for the D. Lipinski Soft-
ware Buyers Guide To Sinclair-Timex Products
And Services, that we mentioned in the March/
April '85 issue is: 2737 Susquehanna Rd.,
Roslyn, PA 19001. Price is $20 ppd.
Kirt Olsen, Publisher/Editor of Syntax,
told Time Designs that he intends to con-
tinue publishing the newsletter. He also
mentioned that Syntax (and SQ Magazine) is
up for sale. The last newsletter that Kirt
put out was the November '84 issue. He
told us that the December '84 issue of
Syntax should be out in another month or
so.
Time Designs Magazine would like to
welcome all our Canadian readers "on-board"
who have recently subscribed. The number of
our friends up north grows each day. It
just goes to show you that Canadians know
a good computer when they see one. Happy
Sinclair computing to you all!
ZX81/TS 1000 KEYBOARD
A large number of ZX81/TS 1000 users
have “discovered” perhaps the best keyboard
add-on that has ever been offered for the
price. It is the computer keyboard that
was used with the Texas Instruments 994/a.
They are being sold at surplus electronic
outlets and some Radio Shack stores for the
extremely low price of $2.95 to $5.95 (de-
pending where you obtain one). The challenge
is the installation. We have seen some
nice ideas. Hopefully, we will be able to
print them in an upcoming issue. If you
have a suggestion, send it in and we may
print yours.

SPECIAL REPORT:
2068 IS RETURNING TO U.S.
WNVULUCUUOUCUUOUCOUOUUQUEO00U000000000000000000000E000000 00000 0UEU EEUU
When Bob Dyl of the English Micro
Connection contacted Timex of Portugal
to see if he could obtain supplys of their
new floppy disk system and 2068 “silver
avenger" computer (as so nick-named by
the British computer press), both of which
had been sold in England for several
months, he learned of some very suprising
news. Antonio Gomez, the Managing Director
of Timex Portugal told Bob that they
were in the process of bringing the
2068 and the disk system to the United
States themselves. In fact samples of
each were currently in the hands of
the FCC for approval. At this writing a
Mr. Olivera who is the assistant to Gomez,
is in Waterbury, Conn. at the Timex Corp.
headquarters (which Timex Portugal is using
for their temporary base) to finish
up last minute paperwork, including sign-
ing the FCC certification release papers.
This certainly is a strange situation.
A Timex paradox of sorts. Just a little
over a year ago the Timex Corp. killed
the 2068 in spite of strong support
by both consumers and the computer press.
And now, here is their Portugal counter-
part bringing back almost the same computer
to the American market. It isn't quite
known exactly what Timex (U.S.) role in
Portugal is and what are the controlling
interests. It is known however, that
both Portugal and the U.S. owned Sinclair
technology rights, and when Timex U.S.
dropped out, Portugal continued to use
and produce that technology.
Antonio Gomez told Bob Dyl_ that
if everything goes as planned, _ they
should start shipping units by the end
of May. As far as what marketing strategies
are going to be used, and who will
sell the computers and drives...the de-
tails are sketchy. Most of the Sinclair
vendors that still exist here, have
expressed interest.
The old Timex/Sinclair 2068 that
we are familiar with has maintained
its silver case and keyboard, but has
been retitled simply the "Timex 2068".
6
It's main circuit board has been a complete
redesign, but has maintained the two
ROM system, the sound chip, and the
joystick ports. It now operates on nine
volts instead of fifteen in the original
model. In the cartridge port is a plug-
in type Spectrum emulator board, and
the rear connector has been reconfigured
to be the same as that of a Spectrum.
So basically, what you have is a Spectrum
in 2068 clothes, with some of the subtle
advantages of the 2068 remaining intact.
A nice addition to the Timex 2068
is it's accompanying disk drive system
called the “Timex FDD." It is a four piece
package with a power supply, interface,
controller board, and a 3" Hitachi drive.
The disk operating system is called
(TOS). A CP/M board may be _ released
a little later. Portugal is also planning
to market the disk system for the U.S.
T/S 2068 also, with a suitable interface
for that computer.
Retail pricing for the 2068 and
FDD has not been set as of yet, and Gomez
told Bob Dyl that they were going increase
the prices from which they first estimated.
Reaction has been mixed to this major
announcement by Timex. Criticism and
skepticsm has been voiced by those who
still bear the scars from when Timex left
the computer market a short while ago.
Some disappointment has been expressed
as to the incompatibility with existing
hardware that has been developed over the
past year for the old 2068. But the excite-
ment is spreading for the most part, as
Sinclair users in general here in the U.S.
can expect to see much on it's way as far as
support for the 2068/Spectrum is concerned.
Quite a bit of software and hardware will
no doubt be heading this way from major
English companies.
Time Designs Magazine would like
to express thanks and appreciation to
Bob Dyl of the English Micro Connection,
for releasing this information to the
American Timex and Sinclair users.

INTRODUCTION TO COMPUTER CONTROL
by Bruce C. Taylor
Tucson, Arizona
OK all you T/S 2068 buffs,
dust off that. 2X81 -or T/S:-1008
(excuse me for a moment ZX81 and
T/S 1000 users) and let's do some
serious things with your computer.
No, I'm not talking about doing
your income taxes, balancing your
checkbook or writing your first
novel, When I say serious, I mean
controlling something with your
computer. Although you can use your
L/S 2068... y0ur -Zk8PF ox 7/8--12000
will do the job very nicely too.
Control what, with your com-
puter? Control anything you think
Right be: nace to controd. Your
lights, your garage door, your
coffee pot or even your personal
robot. PERSONAL ROBOT? Yes, your
lowly T/S 1000 (excuse me again
‘ZX81 and T/S 1000 users) is very
capable of nearly anything you want
to control with a computer. Remember
those personal computer experts who
brushed off the Sinclair and Timex
computers as mere "toys" good only
for learning about the basics of
computing, but not for "serious"
computing? Those "experts" now say
you shouldn't tie up a personal conm-
puter with mundane home control tasks.
Well,-the. experts can be correct half
the time.
Even’ in the: face of- current Io
bit and soon to come 32 bit home con-
puters; don't-tet-anyone sell .the:s
bit Z80 CPU computers short. The Z80
based computers are an excellent
choice for control applications. If
you don't believe me, look to Japan
where an assult on the small com-
puter market has been launched with
their MSX (MICROSOFT EXTENDED) con-
puters. One of the prime reasons
they selected the Z80A CPU was be-
cause of it’s potential for control
applications,
In your ZX81 or T/S 1000 con-
puters (include the T/S 1500, T/S
2068 and SPECTRUM too) you have the
makings of a very capable computer
control system. ALl you. need to get
started "interfacing with the world"
is to add an input/output (I/0)
board to your computer.
But wait a minute, before I
launch into the details, you may
have the following question. Why
build a control project from scratch
when I can buy a robot or home con-
trol/security system out of a box?
First of all, it will probably be
cheaper to build it yourself. Also,
if you are inclined to tinker and
build, you can continually expand
and upgrade your system as you de-
Sire. This allows you to take ad-
vantage of new equipment/component
advances, not to mention software
upgrades.
Foy ¢€xample, if you: buiit a
personal robot as I have done, you
may have designed the controlling
software to use the input avoidance
technique of navigating around the
house. With the addition of a range
measuring device, like the Polaroid
Ultrasonic Ranging Device, you can
advance the navigation capabilities
to a goal seeking ability... Ties can
be done by modifying the software
so that the robot seeks open areas
to navigate through, much like you
seek a doorway as opposed to avoid-
ing walls in a roon.
Back to the problem of building
an I/O interface for your computer.
Several options are available. One
was described in a series of articles
in RADIO-ELECTRONICS MAGAZINE last
year. Another is an inexpensive I/0
board offered by BUDGET ROBOTICS §&
COMPUTING of Tucson, Arizona. Both
offer eight parallel lines of input
and output, and use simple machine
code subroutines to give a very fast
I/O capability. How fast? The Budget
Robotics board includes documentation
for a simple optical encoder that can
measure inputs up to several hundred
pulses a second, and all for only a
few dollars. Is that fast enough and
cheap enough to entice you to get on
with this computer control area of
interest ?
Budget Robotics in fact offers
an expanding line of peripherals in-
cluding a buffered buss expansion
board (currently for Zx81, T/S 1000
and T/S 1500) to allow you to add
an almost limitless number of items
in your computer control project.
In fact, I have written a book de-
scribing these and other projects,
to be published by early 1986 by
TAB BOOKS... The centerpiece of. the
book is "H.EON.R.~Ys" am ent eras ly

it, a Sinclair ZX81. Hardware and

of articles in T-S HORIZONS Magazine.
Using Paul's non-volitale memory
board, control routines can be cre-
ated and saved for instant loading
into computer memory and easily
changed as upgrades to your control
project are needed. This method is
cheaper and easier than burning
Programmable Read Only Memory (PROM)
chips, or trying to buy Electrically
Eraseable PROM (E2PROM) chips.
Other expansion boards and I/0
circuits can be used which will also
do a good job. John Oliger described

applications. Wiring of the 8255
circuit is included in Budget Robotics

described in my book.
To give you an idea of the
range of control applications I am
proposing, refer to Figure 1 as you ?

will want to add an expansion board

least one input/output (I/0) board.

by John McMichael
The following is a compact machine Bozeman, Montana
code routine that provides a 2068 user
with digital joystick position information
and button status at machine code _ speeds.
It was originally designed to be of
use in upgrading game programs from key-
board control to joystick control.
Basically, the two joysticks are FIG. 2 - JOYSTICK DATA LOCATIONS

A GRAPHICS PROBLEM for the T/S2068
A "SERIOUS" GRAPHICS DISPLAY FOR THE 2068 AND 2040 PRINTER
by Dick F.
Wagner
Canby, Oregon
One of my pet beefs with many
computer programmers is their lack of con-
cern for identifying the basis for their
programs. The display of the formulas/
equations used, would help the user decide
if the program is indeed the one needed
for his -{or her) calculations. It is
often not easy to pick this information
out of the program because of the way
the programmer had to chop up the formula/
equation. Also there should not be the need
to spend a lot of time trying to identify
the information needed.
The following program is substantiated
as to formulas. This makes it easy to sub-
stitue as you wish. However the problem is
complex in that several sytems are involved
in developing a problem display. The
formal graph with x and y axis, notations
and scales provide an example for similar
displays. The derivations for generating
an equilateral triangle as well as drawing
an inner and outer circle touching the tri-
angle shows the steps. The chart coordinates
have suitable divisions marked off, as well
as enhancing every 5th division. The end
product, instead of just displaying a tri-
angle and 2 circles, shows the result
of calculating a problem with interpretive
results.
The first step is to draw the
x and y axis, scales, divisions and
headings. The radius of the outer circle
is to be 40 inches. Use a scale of
one pixel as one inch. Therefore, we
need to provide for a figure 80 by
80. For a nice balance, place the circle
center at 95 (x axis) and 80 (y axis).
To allow space for x and y axis data
place the x axis 20 and the, y axis
at 25. Position markers every 10'pixels .
(inches) and enhance every 5th mark.
Remember that all positions are with
respect to 0,0 for PLOT (bottom left
corner) and 0,0 for PRINT (top left
corner).
A A et a
a]
Lines 10-190 generate the axis,
markers, axis numbers and axis names.
Many lines include a printer correction
factor of 1.24 (Timex 2040 Printer).
This is necessary to produce a symetrical
image. After all, who wants to excuse
his (or her) equipment for making egg-
shaped circles and non-equilateral tri-
angles?
. To review the derivation of the
correction factor, just DRAW a _ square
of good size, and make a printer copy.
Measure the height and width (use a dec-—
imal or metric scale). The ratio of
these dimensions is the correction factor.
Now re-draw the square, using this mul-
tiplyer. For example, assume the square
was drawn with PLOT 30,30:DRAW 80,0:
DRAW 0,80: DRAW -80,0: DRAW O,-80. For
the 2040 Printer, you would change the
lst and 3rd DRAW to 1.24*80,0 and -80*
1.24,0. Check your printer to see
if it is the same.
Lines 45-110 put in the markers
on the x axis, and lines 120-190 put in
the y axis markers. RUN the _ program
from 10-190 and confirm proper display.
CLS and the "graph paper" is now ready
to plot the 3 figures. It is now time to
calculate the dimensions for the figures
and decide where to place them. Remember
that we are going to have a display
with measuring capability of the finished
s
1 9 figures.
“4
Calculations start with determining
the sides of the equilateral triangle
from one dimension, the radius of the
outer circle. That has been given as 40
inches (3rd paragraph). Key in lines 395-
470. DELETE later if desired. This
part will draw a right triangle (any
scale) and from the hypotenuse (the
radius of the outer circle), we can
determine % the base and the radius
of the inner circle.
These formulas will be used:
b=a*SIN B/SIN A
c=a*SIN C/SIN A
circle=r*COS 2*PI,r*SIN 2*PI
a is radius (40), b is % the base
of the equilateral triangle and c is the
radius of the inner circle. All is
shown on the sketch. We know that
an equilateral triangle has all angles
equal to 60 degrees. A line drawn
vertically bisecting the base will also
pass thru the circle center. RUN the pro-
gram from 395, and display the triangle
along with the calculations. Angle B may
not be evident, so consider B as 4 of
one third of 360 degrees.
rene
There are all the dimensions’ required.
Lines 200-320 draw the 3 figures
with center at 95,80.
Lines 330-370 put in a title, initials
(yours) and date.
I think you will agree that our
computers can produce a product’ that
takes it out of just a visual display.

SLOT MACHINE

Sacramento, California
REAL LAS VEGAS STYLE CASINO ENTERTAINMENT!
The program is a slot machine which plays 25 cent
pieces, and keeps track of your winnings and
losses (it even plays a little fanfare if you hit
the jackpot). The odds ought to be pretty close
to Nevada odds, and should keep the children
quiet for hours. It is important to get the
spacing just right in line 15, since the "fruit"
which appear in the slot machine windows are
"slices" of the character string "A$". (EDITOR'S
NOTE: this listing was made with a printer
that doesn't use @" for zero. So be careful
when entering numbers in this program.)

I sent $39 to VAMP Inc.,
and .U days later rT receiver <2
package containing a circuit
board, a package containing
resistors, capacitors, and a
few other parts, along with an
eight page instruction manual
with schematics. After a couple
hours of assembling the PC board
and mounting a TV/monitor switch,
and, the-PC. board....1.was. ready
to make the circuit/TV con-
nechiogs.
Next, I went out and paid
$8.50. for .a..Sams .Photofact.,..for
my model of TV (Sanyo). The in-
struction-manual tells. where,
and shows typical examples of
where to make the connections.
I would still recommend that you
either have experience with TV's
or know someone who has, and
will, help.you.with this part, of
the project. I made three. wrong
connections: before getting it
right.
The final. result.as- a color
monitor/TV with a picture every

TASWORD TWO TIPS
by William D. Erickson
and
Paul -T = Bei ¢khs6n 5
Decatur, Georgia
Many of us that use TASWORD TWO
are bothered by one thing that spoils
all the fun. This is the fact that once
you have printed something on your 80 col.
printer, you can not again print with
your T/S 2040 Printer without going
through a big hassel. Also, many of
the command functions of the program
also produce the same result and _ leave
the user who only has the T/S 2040
Printer between a rock and a hard place.
To correct this problem, go to
the main menu by using SYMBOL-SHIFT
A, exit to BASIC by pressing b,_ then
add this line to the BASIC. portion
of the program:
29 POKE 26703,0 : POKE 26704,5
Now GOTO 25, and save this
of the program by pressing "t".
Now any time your T/S 2040 fails
to print, all you have to do is use:
SYMBOL-SHIFT A, then press "y" to return
to your text and print to your hearts
content. This in no way interferes with
your 80 col. printer.

Set right margin to 32 columns.
Set window to a 32 col. screen.
Stay in this mode when you print
your text. All other aspects re-
main the same. Large print still
works; ‘jst. more so.
PRO/FILE 2068 is a very special program,
that the author Thomas B. Woods (no relation)
has painstakingly put together for owners of
the T/S 2068. Supplied with the software on
cassette is a real gem of a users manual.
It is 143 pages long and makes for some in-
teresting reading.
What does PRO/FILE 2068 do? Tom goes
into great detail in the manual describing
what it is all about. Basically, it is a
filing program or "data base". The possible
applications are almost endless. These
examples are given: filing mailing lists,
business transactions, inventories, ham
radio logs, and all kinds of records.
Right away, you will probably notice,
that this data base is a little different
than some others that were previously avail-
able. One that I think everyone has used at
» one time or other, is Timex's VU-FILE. The
way VU-FILE works is by setting up “data
fields" that the user specifys when setting
up his file. Once the data fields are set,
it is a real pain to go back and change or
correct the files parameters, without totally
redoing the whole thing. PRO/FILE doesn't
use "data fields", but instead stores each
individual file or record in individual screen
displays. To change or delete is very easy
with screen displays.

PRO/FILE 2068
reviewed by Tim Woods
Colton, Oregon
I gave PRO/FILE 2068 a little test drive,
I entered 20 of my all time favorite songs
as individual files each. Included in the
file was the songs title, author, the year
it came out, and a few lines from each one.
I found that entering the data was easy,
but I constantly had to refer to the manual
to make sure everything was right. I am sure
an avid PRO/FILE user would remember all of
the commands...but as a beginner, I stumbled
a bit. When all the data had been entered,
I began to experiment with some of the
multi-word search functions. When I asked
for a particular song, it immediately
flashed up on the screen.
PRO/FILE has a total capacity of 28,000
bytes! It is compatible with the Timex 2040
Printer or any number of Centronic inter-
faces and printers.
If you have a special application for
PRO/FILE, I am sure information on it would
be found in the users manual. It goes into
great detail. There is even the program
listing of the actual program, that can
be altered to suit particualar tastes.
PRO/FILE 2068 is an exceptional value
at $29.95. Its file searching and retrieving
capabilities are very superior to other
data bases that I have seen.

BILL'S COUPON MAGIC is a program
written by Bill Erickson of Decatur, GA
for the T/S 2068. He sells his own program
through HD SOFTWARE, for $14.95 + $1.50
for postage. His address is: 1445 Oldfield
Road, Decatur, GA 30030.
This program is a lot more than
it first appeared. Actually, there are
three differenct functions. The first one
is a shopping list that you can enter
your items in categories and include the
estimated cost of each item. When you are
finished, it will give you the estimated
amount of money you need to take with
you to the store. There is an example
provided for easy reference. The second
feature is the coupon manager. It is
very comprehensive and allows you to store
up to 99 coupons with a description apiece.
Then you can add coupons to the file or de-
lete old expired ones with the search option
Finally, the third function is an all pur-
pose list manager for anything that suits
your fancy.
All of the lists can be sent to the
2040 Printer. You can also save all your
data on tape. The program comes with very
good documentation.
COUPON MAGIC is an attempt at a
useful program. At first, I had visions
of sitting down and clipping coupons and
tediously entering each one into the com-
puter. This seems like it would be a time
consuming chore. I feel this program has a
lot more potential being a list manager.
Mr. Erickson has programmed some
very nice screen displays for this program,
and I really liked the "women with shopping
carts” design. Ali~ in ail thie is a
nice software package.

THE DEALER’S DEN
THE DEALER'S DEN
is a
program written by Timothy Kessler
card game
for
the T/S 2068. It is sold exclusively
by WMJ DATA SYSTEMS, 4 Butterfly Drive,
Hauppauge, New York 11788. It sells for
$19.95 ppd. and there is also a version
available for the Commodore 64.
On side one of the cassette tape,
is the main program THE DEALER'S DEN.
You play four hands of Poker against
the dealers one hand. You can throw away
unwanted cards once for each hand. You
can also select a bet. At the beginning,
of the program is a table that shows
what combination of cards get what value.
Iam not exaggerating when I _ say
that THE DEALER'S DEN is’ genuine fun.
Although, I must admit that I am ae card
game fanatic. When I started playing this
one, they couldn't tear me away from the
screen!
On side two is
DRAW POKER. It is

hand against the dealers hand. It

I preferred the first game.
The graphics for these programs are
very good. About the best I have seen for
card games on the Sinclair. There is even
a little animated card-shuffling sequence
while the program is loading. I would
recommend that you do use a quality mon-
itor, due to the high resolution of some

THE
DAMCO/ROTRONICS WAFADRIVE
REVIEWED
by Tim Woods
Colton,
If you have a very limited work
area dedicated to your 2068 computer,
or have a small home business, the following
product may be of particular interest
to you. It is the Rotronics Wafadrive
mass-—storage system from England. I pur-
chased our unit from Damco’ Enterprises
(67 Bradley Ct., Fall River, MA, 02720),
who is the exclusive distributor of the
Wafadrive here in the U.S. Damco has
put together a special package that allows
the Rotronics Wafadrive to operate on the
T/S 2068, since the system was originally
designed for the Sinclair ZX Spectrum.
This package includes all of the "goodies"
that come with the stock Wafadrive (which
we will discuss shortly) plus a cartridge-
style Spectrum emulator, and an adapter
for the 2068's expansion port. The Spectrum
and the Timex have different rear-edge
ports.
When the Rotronics Wafadrive arrived
in the mail, I was first struck by
the size of the box it came in. Very
small, to say the least. And the unit
itself is quite compact. It reminds me of
a Tupperware container with a lid (only
black). The old saying, "good things
come in little packages," seems to fit here.
The Rotronics has not just one drive,
but two. They are the "stringy floppy"
type, which use special micro-cartridges
(or wafers) designed by Entrepo. The
Wafadrives are custom manufactured by BSR
(the audio company) for Rotronics. Just
for your information, A & J Microdrive
uses the exact same wafers in their
system for the 2068, but the similarity
stops there.
Along with the dual drives, there
is also a built in Centronics parallel
printer interface and a R232 serial inter-
face. The ports for these interfaces
are at the rear of the unit along with
a normal Spectrum expansion port, to
which a Timex 2040 or ZX Printer can
be attached. On the front of the Rotronics
Oregon
are the two Wafadrive slots
A and B respectively), along with
LED's: one for power on,
two designating which drive
Protruding from the case,
(drives
three
and the other
is active.
just below
the drives, is a very short (about
four inches) cable with the special
adapter already connected to the end.
This is what plugs into the rear of
the 2068. Placement of the Rotronics
Wafadrive is limited to directly behind
the computer. For my installation,it posed
a slight problem, but shortly corrected
by moving the monitor off to one side.
Also in the same little box came two
wafers. One is blank, and the other
is a free word processor program from
Softek, which is cusomized to work with
the Rotronics. It is supplied with a 40
page manual, and is fairly comprehensive
(ie. 64 col., auto word warap/justification,
page numbering, screen editor, block
Operations, ect.). This is a nice touch,
to include a program that can be used
right away with the system.
A 68 page manual is provided for the
Wafadrive. The manual is spiral bound,
and is clearly written and_ suprisingly
detailed...giving some examples as it
covers each concept.
You may be wondering what a_ system
like this costs. Especially with all
of the extras that are included. It
is only $229.95 from Damco, plus $5.00
for postage. I also ordered the optional
Centronics. “abie- “for $12.95, If* you
are the owner of a Spectrum, there
is a version of the Wafadrive for $169.95.
For those of you who already have an EMU-1
or OMNI emulator, there is a_ sytem
available for $199.95.
How does it all stack up? Very
well indeed. The Wafadrives have their
own operating system (WOS) in ROM, which
is similar to disk operating systems
used by other computers. Extended BASIC
commands are used and typed in from
keywords on the 2068 that were originally
reserved for use with the Sinclair Micro-
drives. These are CAT, FORMAT, OPEN,
CLOSED, ect., along with standard commands
like LOAD, SAVE, MERGE, and VERIFY.
The symbols "#" and "*" are also used.
The following is an example of
a command that is used to ready a
blank wafer for transferring data:
FORMAT* "aswafername"
"a" is used to denote which drive is being
activated.
Loading time was fast. Transfer
baud rate is rated at 18k. I _ timed
the supplied word processor program,
and it loaded in 30 seconds. A comparable
cassette program would take three minutes
or longer.
Wafers are available in three sizes
(or storage capacities): 16k, 64k, 128k.
They appear to be rugged for their
tiny size, and have a plastic sliding
dust cover. A wafer has a continuous
loop of magnetic tape inside, and operates
on a principle much like the old eight-
track audio tapes. The shorter tapes
will load files much faster than say
the 128k length.
Using the Centronics interface was
a snap. I hooked it up to my TEAL
model 270 electronic typewriter/daisy
wheel printer via the optional cable.
The interface will send standard ASCII
codes to the printer using LPRINT, LLIST,
some BASIC lines using "stream" channels,
or block commands in the supplied word
processor software. Since this is a "no-
frill" type interface, it doesn't include
smart software (like the Aerco interface),
that allows you to execute graphics screen
dumps, ect. with dot matrix printers.
These functions would have to be developed
by further programming and _ software.
I didn't give the RS232 interface
a try, Since I don't have a _ compatible
peripheral. It should be pointed out
that it is a bidirectional type, and
baud rate is selectable.
Most prospective buyers would probably
be concerned about cassette software
compatibility. First of all, take into
consideration that this is a Spectrum
system. Secondly, commercial programs
are usually protected against making
back-up copies of any kind (cassette
or wafer). You do have the following
options:
1. Make wafer copies of Spectrum
programs that have the option for making
back-ups.
2. Use a "header-reader" type program
to help you BREAK and SAVE commercial
cassette software for the Spectrum.
3. Any Spectrum program that you can
BREAK and SAVE, may be transferred to wafer.
4. Some software for the Timex
can be saved on wafer. This includes
a few machine code programs, and most
all of the BASIC programs. For eample,
I made a wafer copy of programs from
the "Great Game And Graphics Show" by JRC
Software.
You may also make copies from wafer
to wafer, simply by using the MOVE
command. Commercial software is being
developed and sold on Rotronics’ type
wafers now. Damco has a list and prices
of several titles that they carry in stock.
Much could be said about the Rotronics
Wafadrive. More info than we obviously
have space in the magazine for. So,
I will close, leaving you with a few
thoughts to consider. First, the Rotronics
is a little faster and lower in price
than the A & J model 2000 (if you
20
were to add an additional drive, printer
interface, ect.). The Rotronics is about
half the price of a good disk system
with only a single drive, but not nearly
as fast as floppy disks. It is about
the same price as a complete Sinclair
Microdrive system, but the Rotronics
comes with more features like the built
in Centronics interface and free word
processor. Also take into consideration
that you also receive Spectrum emulation
and a Spectrum expansion port...this
will open a whole new world of information
for the T/S 2068.
Over all, the features that I
liked best were the units small (all-
in-one) size, and the ease in which
the Rotronics filed and retrieved data.
The price should also be within reach of
most Timex users budgets.
Good work Rotronics and Damco.
©
Good news for T/S users who have
installed the ROMSWITCH or a Spectrum
ROM in their computers. They can now
use the Sinclair ZX Microdrives...without
the added cost of purchasing an. emulator.
The method is a brand new Microdrive
Adapter available from English Micro
Connection (15 Kilburn Ct., Newport,
RI 02840), for only $35 ppd. The Adapter
is a standard "twister" type Spectrum
expansion port board, with the addition
of a special circuit that includes a 74LS10
IC, a diode, and a resistor. The circuit
was designed by John Oliger, and was
incorporated on the board by Doug Dewey,
who is the manufacturer of the Microdrive
Adapter. Now the ROMSWITCH, Spectrum
ROM's and OMNI emulators can operate
the Interface One, Microdrives, and other
English peripherals on their 2068, without
a hitch! The English Micro Connection
also carries a selection of Sinclair
merchandise including the Microdrives
and the Spectrum Plus computer. Write
for details.

TS 2068 / SPECTRUM -WARES
The Software Supermarket in London,
England has just recently changed their
name to SPEEDYSOFT. They do a large
overseas mail order business, and accept
American credit card numbers. Their new-
est software catalog features 24 Spectrum
programs newly released. For details,
write to: Speedysoft, 87 Howard's Lane,
London SW15 6NU England.
Time Designs Magazine will be re-
viewing some more Spectrum programs in
our next issue. Since there is’ such
a wide variety of titles available from
England, reading a report from a trusted
reviewer before purchasing, makes good
sense. After all, money doesn't grow
on trees. As of this writing the American
dollar compared to the British pound
was $1.22 (a slight increase).

(.for the TIMEX COLOR COMPUTER.)
Up till now, JRC SOFTWARE, has disliked
text editors written in BASIC. Since
they use string handling functions, you
get an annoying delay between each key-
stroke. Letters get missed. These
editors also greatly limit how much of
your memory can be dedicated to text.
So typing long papers may be impossible.
The JRC SOFTWARE EASY EDITOR, however,
ig based on a completely different
concept than other editors. It is
probably the fastest, most efficient,
and easiest text editing system ever
written in BASIC. It also has some
interesting features for ease of use,
such as a bold character option for the
2040 printer. JRC will adapt to your
brand of printer if necessary!
2. ***TOUCH TYPE LEARNING GAME***
Even if you're not a typist now, you
can learn to touch type on the 2068.
This program will introduce you to 197
symbols and keep track of your progress
on each. Weak keys are reviewed more
often than others. With practice you
will be able to touch type BASIC pro-
erams, which is much easier and handier
than the “hunt and peck” method.
Although this may be one of the most
practical and educational programs you
can buy for the 2068, keep in mind that
it ig a GAME and a fun one too. There
is even an option for kids that just
teaches the use of the keyboard without
home-row drills. You and your family
won't tire of this program overnight.
p Ise *###HTI-RES LANDER***
Why settle for games that use block
eraphics? The JRC SOFTWARE version of
the classic lunar lander features a ship
that moves pixel by pixel. With that
kind of realism, you have to have a soft
touch to land. Plus patience. And it
gets harder every round! Fortunately
for novice astronauts, there are two
levels. There is the repular “hard”
option and an “easy” option intended for
children. (But you can practice on
‘easy’ when no one is looking.)

Paint and draw with COLORSKETCH. Use
your joystick and over a dozen single
keystroke commands. Save and load
screens easily.
How good are you at avoiding TIMY THE
TRASH COMPACTOR? Can you eat all the
garbage before he gets you? The large
animated characters will entertain
children, but adults will get some fun
out of it too.
Do you like challenge? DODCGE‘EM is a
fast and difficult race game. Gets
progressively harder to master and
remembers highest five scores. Plus
JRC SOFTWARE added a new surprising
twist to this classic race game.
### OSCILLOSCOPE ###
This was a big hit on the 10CG. Now
it's available for the 2068! It isn't
every day that you see real time three
dimensional rotation. Although the
OSCILLOSCOPE program isn't a real work-
ing oscilloscope, it does have similar
displays and dozens of patterns are
possible. The main difference is that
JRC SOFTWARE added a third dimension to
the view. Impress everyone with the
capability of your TIMEX computer!
### THE GREAT GRAPHICS SHOW ***
Every type of graphics demonstration
that can be imagined, from flashing
displays to three dimensional cities,
has been put together in one fascinat-
ing and eye catching program. Explore
the 2068 in ways not thought possible.
Rather than spending months doing
these yourself, you can buy the pro-
enna
gram and find out how they're done!

Integrated System
The Wafadrive is a
complete system which
contains the micro interface,
two 128K drives, RS232 and
Centronics ports, all in one
attractively-styled, compact
unit. There is a minimum of
connecting leads and no extra
boxes to clutter the desk top.
Like the majority of profes-
sional systems, the units are
dual drive. This offers the opti-
mum balance between
system flexibility and cost.
Built-in serial and parallel
interfaces allow the direct
connection of just about any
popular printer.
Send a 22cent stamp for
a full color brochure and
information on software and
accessories.
Fast and Reliable
The Wafadrive achieves
very fast loading and saving,
but not at the expense of
reliability. Extensive research
and the use of high grade
materials ensure that the
Wafadrive will give years of
dependable operation. Data
integrity is on a par with
floppy disk. The fully inter-
changeable wafers are avail-
able in three sizes-128K, 64K
and 16K. Low capacity
wafers give faster access.
They are therefore most
suitable for program develop-
ment applications. The high
Capacity wafers are suitable
for more general data storage.
Loading rate is approximately
2K per second-almost twice
as fast as similar products.
Spectrum Emulation
The Wafadrive includes
the Omni/Emu Cartridge.
This enables the Timex 2068
to run thousands of Spectrum
programs. The rear edge
connection is compatible
with Spectrum Hardware as
well as allowing use of the
2040 printer.
Wafadrive for the Timex
2068 and the 16/48K Spectrum
are available now.
