American User Groups, providing news and software sup-
port to the T/S community in a VOLUME of four

forum for the exchange of knowledge, building and
maintaining of software libraries. Providing vendors,

the vendors, that provide the pecuniary support for this
newsletter. Vendors and developers receive this newsletter
free of charge, though contribution from vendors and user
groups is gratefully accepted. Please support our vendors
and service providers whenever possible.

In the mid 80's 1 organized a Sinclair Club of young
people and we had a wonderful time in our early, tumbling
coding, -wiring in keyboards, and devising clips to keep
connector cable plugs from slipping,

I got seduced into Pascal coding on a Kayp.ro and gavs
all my Sinclair equipment to the local community college
museum .... which later silently got rid of the collection
When TS- 1000s started to be remaindered off at giveaway

Dear readers of ZQAJ I'm searching for
information about the HS-1. I've found the
advertisement shown above in the American magazine
I SYNC March/ April 1984. According to the text HS-1
will connect two TS 10G0/ZX81 and you can operate \
your program in FAST mode on one of the computers,
while the other one will work in SLOW mode for a
continuous display.

We have already tried to discuss the function in
the ZX81 mailing list but nobody ever has seen a
working HS-1 . Maybe it uses /BUSRQ and /BUSAK,
but nobody really knows. J hope one of you will
.know more about HS- 1 , or even better will have a HS-
1 (dead or alive). I would be very glad, if someone of
yon could help- me with more information.
Thanks in advance, Suietairly yours

Hi everyone, I had a thought about something and I
wanted to run this by everybody and see what people
thought. 1 have just about most of the Time Designs'
magazines and 1 think all of the "Update' magazines also.
There is a lot of great Timex/Sinclair info in those
magazines, as well as info on all of the Sinclair machines
(but Time Designs as you know focused more on the
TS2068).

Wouldn't it be great if a web she could be created,
that would have ail of the content of these magazines on it?
J think it might be harder to get the OK from the people
that ran Update, but Time Designs has been out of print for
over 10 years now and 1 am sure the editors) could
probably care less now if all of this were online. 1 do not
have a scanner, but they are cheap and I would gladly buy
one for this project 1 don't know, 1 just think there is too
much good info in those magazines for them to just sit and
collect dust. It would be a good source of reference
material on the Timex computers to have these online.
Any comments? see va,

.Luke Perry

Lute,

I think that's a great project. You could host it on my
server also, if you fifce. ftM fee coof if you could ran an OCR.

mi It, also, so chat Ihe data cm be searched, hut I kmw wm.
might be difficult Perhaps you could HTMLize the indexes
ot the issues so at least some into is se&rchaofe..
It's definitely going to take you some time, though. And
space, Fd gander each page of a scao can iafae up a sizable
chunk of memory. If you need an OCR software I have one
that runs ofc under windows. Let me fcnow offline..

Hi

It would he great to have all Time Design magazines
on the net (t own two numbers). Of course this will get you
lots of time

This project is simitar with the Spanish MicmHobby
magazines. I have read the Spanish Sinclair newsgroup and

liobbyPress doesn't authorize the publication of
MicroHobby magazines in the internet.

'lie Film Annual rJaMtee"! ZX-TEAM meeting
was Ma ift Dietges,, Qmmm March 2 m through
4 :h - mid 1 was there! I 've always wanted to alteM
a ZX-TEAM meeting, and this year, after getting a
preliminary ""'okay'" from the Director of finance (my
wife), I sent an inquiry to Peter Liebert-Adelt, who
organizes the meeting each year. Peter very
enthusiastically extended an invitation to me, and after
hustling up a passport, tickets, etc. 1 found myself halfway
over the Atlantic Ocean, on an eight-hour eastern-bound
flight

"he German railroad system is very efficient and
user friendly. After my arrival at the Frankfurt-
am-Mam Airport 1 only had to go down one floor
to eateh a train to the ftmnfefiat Central Railway Station
Another train took me from there to Fuida, the largest city
near the meeting-place in Dieiges. AH in ail it only took
about three tars for me to clmm my baggage, get through
customs, exchange ccareney, m& travel to the WuU&
Station, where Peter was to pick me up on his way to the
meeting.

TIP wasn t ^ on S until 1 was approached by a couple of
|| suspicious-looking guys One of them - Peter -
„Jti_ pulled a ZXSl from inside his jacket and asked if I '
knew where tig ©add onload a hmch of these. They
hustled my luggage into Peter's van, which also contained
Peter's wife Ruth and three other ZX~T£AMers, After a
short drive we were at the lodge in Dietges.

y this time it was about six o'clock on Friday
night. 'The: meeting room was fall of people
bustling around, getting acquainted, and setting up
the equipment they had brought to show off. After dinner
and a couple of more hours • of looking over people's
shoulders I had to pack it in since I'd been up for about 35
hours. I can never sleep on planes . .

aturday morning 1 was jet-lagged and didn't get up
.until after nine. Breakfast was almost over but 1
managed to scarf a few roils and a pot of coffee

(

God the Germans make coffee the same way we do

in the States) before the food was cleared away.
Pandemonium then ensued - throughout the day people
were coming and going, trading information, hardware,
software- etc. Additionally there were a number of
demonstrations.

m iischer was there to present rae with an IBM
hard drive ana conttoier tor my ZX8i 0 had
traded Mm mum State-side gmtHm m a^vaacej
and also to off Ms ether, inventions including ihe
"ZXS! laptop^ which has a hinged LCD screen attached!
I think well see a lot more great projects from Kai.

X-TEAM. feuader loacMm MerM md Gerhard
^Dohnfce both had ZXvos on display These are
srapressue and powerful machines with
features including an fl>E hard drive, 3.5" Soppy drive, J
MB RAM, AT-styfe keyboard interface, LCD screen,
serial and parallel ports, dsd an impro ved n>is cottnecmr
Gemot Feucht set up a 2X81 with a modem attached and

sssed ft m *£af mm the EC-TEAM MaMhmL a 'M-bmir
BBS, tatbsaoft-ZXSl department, Woitgang md Mm&m
Matter pte ^Woisoteam*!* tf&ff seatf up the Socman
Profi Quh, showed off their Sam Coupe which sported a
.340 MB. hard drive, CD-ROM. drives, and lo-dst sound.

f]||~ airway through the day the demos began, with
jli Christof Odenthai, Markus Schiuharl, Joachim
ilLand Gemot each bringing out then robots (or
^hoiesT as the Germans sayjt Philip Midrane gave a
demonstration of a DOSAVindows-based C compiler
which produces ZXSi. code. Koally, Gemot snowed a
film of some of his other ZXSl -based robotics projects,
The rest of the afternoon and evening consisted of more
people coming and going, lots of friendly trading, and for
as* a graefcig one-hour crash, coucse m MEFi'SDGS at the
hands of the master, Joachim himself.

'he MEFISDGS CiVfErklFIScherDOSi operating
system, developed by Joachim MerM md Km
Fischer, is p&wsM hut *er$» dmptz £» use, tt&
arrow keys may be used to navigate through subdirectories
mi LOAD programs, or commands can fee issued' direetlf
from the command prompt. MEFISDGS commands can
also be called from within BASIC programs, so its easy to
make a program auto-run, for example. MEFISDOS was
iflduded. m the hard, drive Interface f received from Km,
and 1 have been using it on a daily basis for over two
weeks I have yet to find any bugs or other anomalies
The two main limitations 1 know of are. eight-character-
max file names, and fife size is. limited to l€ KB., 'the
latter isn't really a factor: since hard drive file ifti & fist,
^chaining'" programs is easy and practical, so it's
conceivable that a "program" - really a group of them -
could consist* of i MB of BASIC code, or more!

i unday morning there was just enough time to eat,
pack, clean the lodge, and say goodbye to the other
ZX-TEAM members. I learned so much and met so
many fascinating and genuinely helpful people, and in

such a snort usih

Everyone was so willing to share
whatever they had, which is especially remarkable
considering that i don't speak German, and we had to
converse in English 111 treasure this experience for the
rest of my life,

'X-TEAM is a great .group of people who are taking
£m ZXSl far beyond anything Uncle Clive ever
breamed of. mjrni^ who lias the slightest chance
rfattnflog a meeting should start pknnhig now.
: . Hm vmwt regret it for a minute.

f WI t is sometimes useful to be able to switch the ZK
■■Spectrum keyboard's cap mode on and off so as to
HH control the keys for which a program is testing. Caps
mode is controlled by the system variable FLAGS2 at
location 23658 (#5C6AL The instruction POKE 23658,8
sets caps mode but also resets all the other flags in that
register.

there is a ROM routine which can be called using
RANDOMIZE USR 4.317 but if caps mode is
already set, this call will reset it
The solution .is a short machine code routine that can be
loaded anywhere in memory. It consists of just three
instructions:

LD HL,23658

S£T£,{HL)

RET

suitable program to set up this routine would look
like this :

i "■ 1 1

1 000 LET start = any suitable address
1 0 1 0 FOR a - start TO siart+5
J 020 READ b: POKE a,b
mm NEXT a

1040 DATA 33,106,92,203,222,201

David Solly

Cmode can then fee set by
JllIlM RANDOMIZE USR (start).. To force
■ the Spectrum into lower case mode

change 222 to 1 58 in the data in line 1040.

This machine code routine renders itself nicely into
the HiSoft Pascal procedure listed below. If the value
passed to the Boolean variable ON is TRUE then the caps
lock is switched on Tf the value passed is FALSE then the
caps lock is switched off.

PROCEDURE CAPSLOCK(ON : BOOLEAN),

his procedure will set the XX Spectrum
and the T/S 2068 caps lock on when ON
is TRUE and off when ON" is FALSE.

)

BEGIN

IF ON = TRUE THEN
1NLINE(#2 1 , #6A, #5C, { LD ML, 5C6A \
#CB, #DEL |SET3,<HL)j

IF ON = FALSE THEN
INLFN£{#2 1 , #6A, #5C, { LD HL, 5C6A }
#€B, #9E); |RES J, (HL)}

END,

Ifhe following HiSoft Pascal, source code augments
m and provides some alternative methods to the
ML graphic functions and procedures provided in the
Turtle Graphics package that is supplied with HiSoft's
Pascal Version 1.. 7M compiler for the ZX Spectrum.

CIRCLE{X,Y,R) draws a circle, center X,Y and radius
R

DISK(X,Y,R) draws a series of circles at center
X,Y in an attempt to fin a disk of radius R

PLOT(X,Y) is a relative draw like the ZX

Spectmms DRAW function but no third
parameter is allowed so curves cannot be drawn

LlME{Xl,Yi,X2,¥2)4raws a straight line between XI, Y I
and X2,Y2

FILL|Xi,YI,X2 J Y2) shades a rectangle. XI, Yl specifies
the bottom left hand comer and X2, Y2 is the top
right comer .

COPY is identical to the BASIC COPY function

est of the procedures work by calling the
appropriate ZX Spectrum ROM subroutines.

Others use a procedure which has already

3 Highlighting all the lines within a FOR - NEXT loop..

"*fy&$ effect of a control code is not confined to a single line so if you
m wish to highlight a particular line then you must include two changes,
/ one to produce the effect and another to restore the original

conditions. Each of these control codes takes up two bytes of memory and

very strange effects can be caused by deleting just one of the bytes.

ABSTRACT Or HIE DISCLOSURE

The moisture seosing control for clothes dr,ers charges
a capacfior as moisture level decreases (resistance of ieak-
age path inci cases) until neon bulb fires 10 pube the base i
o£ a switching transistoi to pass enough voitagc Jhrough
a coll in the collector circuit to cause a m^gwifc latch
to open aod shut down tbe dryer. A voiragi network
forward biases (he transistor to pass a $mixll amount of
carrem through the coil — ies? than required to open the 2
ktch — which varies with variation of suppjy voltage to
thereby function as a voltage regulator.

The magnetic latch concept is claimed in our applica- " y
fionScr. No, 617.630, filed Fab. 21, 1967,

Background of invention

Moisture sensing controls of this general type are ta

2

to allow for clothes not bridging tlse rings for a period
of time. As the charge builds up on capacitor Q the po-
tential across nsors bulb N 3 increases. Ixad i6 connected
to the other side of K 3 is connected to the base of
transistor Ch throagh resistor R g .

Coll Ki is connected between the DC supply and the
collector of the transistor while the emitter is conuecled
to lead 30, When tube Ka fires, the transistor conducts
and tl«e current ifcwiog Jhrougli coil K> will set up a «?ag-
lictic field opposing the field of penuaneat ruagnel iS.
TJjc pcimaueat magrjet is used to hold switch 20 closed
by attracting a ferrous keeper. V/heo the coil is eaergized
by the transistor, the magoettc fields cancel af«3 a ieu»rc
spring acting on the keeper will open the switch. The
swilch controls energization of the heater 1% and moior
24 connected across l.y Lj. This magnetic latch arrange-
ment is claimed in the aforesaid application. The kick
also controls switch 21 which, vhen opened, de-eneigt'^es
the eoniroh

A small voltsrjre through, the coin K t will not unlatch
the switch. With this in mind, a resistor R 4 Is connected
between leads 26 and 2S. Resistor K 3 is connected be-
tween lead 1$ and grounded lead 30 which connects to
N. Resistors R4 and R$ are connected to act as a voltage
divider to ht3s tlte transistor forward slightly so a small
current flows through K: at normal line voltage. If line
voltage Increases, die Has increases to increase the cur-
rent through the coil (still not enough to unlatch switch
20) and increases the current through resistor Rj which
increases the voltag* drop across Tbis> then, main-
