Hello Abed 

I just got the current issue of the newsletter. It 
looks great as always! I am so very sad to hear of 
Fred Henn's death. We had corresponded many 
times regarding Timex computers and he was always 
very helpful and seemed very genuine. He even 
wrote me a few times just to see how I was doing. 
The Timex/Sinclair community has truly lost a great 

Also, could you please update my email address 
to I hardly check my Yahoo 
account anymore because it is always filled with 
Spam! I noticed in the letters section that someone 
was inquiring about some software. I will contact 
him and see how I can help. 
Thanks Abed and I hope all is well with you. 

Lu k e Perr y 

Dear Abed, 

I enjoy even 7 issue of QLive although my near 
vision does not allow me to use my Timex/Sinclair 
pieces anymore. Your Winter 2001 issue is 
testimony that computer basics are still helpful as 
well as enjoyable. I do miss the programming effort 
I used to enjoy and the wonderful tilings (very 
amazing in fact) that my TS 1000/1 500 and TS2068 
(also two QLs) equipment use to open my eyes and 
mind. Keep up the good work Sincerely

Carol and Frank Davis were involved in a bad 
accident Early Sunday morning while leaving town. 
Condition is bad and they are last known at Intensive 
Care Unit at Dukes Hospital. 
The guy who hit them is not expected to live. 

Mike Ingall 
Sales manager 
FWD Computing _ 

Let me give an update. 

It appears that the hospital sent them home 
much to soon, something having to do with 
insurance only pre-authorizing so many days and the 
doctor not wanting to challenge it. They had Frank's 
sister take them to a doc they know in Kokomo, IN 
and he had the files faxed over to him from the 
Duke's Hospital in Peru (where they were treated). 
Looking thru the files they found that the tests 
showed the bottom vertebrae crushed on Frank, an 

MRI needed to check out the next two up from there 
as they felt they were also damage, the sternum in 
his chest is cracked, cracked ribs with 4 on the right 
side and 3 on the left. With Carol, it is 3 vertebrae 
cracked or partially crushed, neck injuries due to the 
feet of no air bag on the passenger side, crack ribs on 
right side, cracked sternum, and Monday being 
tested for one, if not 2 partially detached retina of 
her eyes. This doctor sent copies of these reports and 
sent them, as well as the Davis's to another doctor 
for checking and he verified the same. Tomorrow is 
another doc appointment for Frank and Carol on 

When Frank and Carol left the hospital they 
were not told of any of the possible spinal injuries, 
or sternums, only that they would probably be a little 
sore there for a few days and here is a prescription 
for Hydrocodene for it and that Carol seemed to 
suddenly have very high blood pressure. So much 
for medical ethics, and as far as insurance goes. ..well 
these days that is a story worse than the bad jokes 
told about lawyers. 

There you have what I know straight from them 
and Frank's sister who just got back to their house 
after a less than exciting day of trips to docs. 

Mike Ingall 
Cards and notes should be sent to: 

Frank & Carol Davis 
FWD Computing 
P.O. Box 17 
. - ^ e ^co JN_46958_ 

Both Carol and Frank were signed up for a 
number of computer shows in the upcoming months 
and asked me to say that they hope to still make it to 
some of them. They lost (it is still being tallied up 
for insurance) over $17 thousand in software as well 
as the Dodge Grand Caravan they usually hauled 
stuff to shows in, so their will be a few obstacles. 

As their sales manager I know they had been 
signed up for 2 shows they already missed, the AGI 
Show in Anderson, IN and the LaPort HamFest in 
Laport, IN. They were next scheduled for an AGI 
Show in 2 1/2 weeks at Lafayette, IN. At this time 
that is doubtful, but a very slim chance, as Frank and 
Carol usually enjoy doing these show's and have 
many friends at them. 

They were also signed up and paid for the 
Dayton ComputerFest in March and AmigaExpo in 
Maryland the end of March as well as planning on 
the CocoFest in May in a place North of Chicago. It 

ZXir QLive Alive!

is hoped they will make some of these. 
So, go ahead and send cards, notes etc, to the 
Mexico. IN address. Thanks all, 

Mike Ingall 

Just a short update. 

Carol has been told that she does not have detached 
retinas in her eyes, but that they were damaged. She 
is scheduled for re-checks even- two months to see if 
it is permanent. Both are healing, but not as fast as 
they would like and are in physical therapy 3 days a 

Both are still being checked by their prospective 
docs once a week also. Not yet ready to drive. 
They may make an appearance at the Dayton 
ComputerFest next weekend. They have someone to 
drive them, do the manual labor and take them back 
to the hotel if too tired out or in too much 
discomfort. This is not for certain. Guess they just 
hate to give up. Still needs doc approval. 
If they do not make it their they are still wanting to 
make the Amiga Exp020G2 in Maryland a few 
weeks after that. Wish them luck, they have 
appreciated hearing of well wishes for them as well 
as cards and flowers, etc. Thanks.

The Z88 Source Beck 

Section 3 



Memory Organization 

The Z88 is based on a Z80 processor running at 
3 .2876 MHz. Hie Z80 lias a 16-bit address buss and can 
directly address 64K of memory. The Z88 can use up to 
4Meg of memory by having 256 banks of 16K. The Z88 
can address 4 such banks at one time. The 64K logical 
address space is divided into the following 4 16K 

Segment 0: Logical addresses &0000 - &3FFF 
Segment 1: Logical addresses &4000 - &7FFF 
Segment 2: Logical addresses &80G0 - &BFFF 
Segment 3: Logical addresses &C000 - &FFFF 

BASIC'S program workspace is arranged in the following

80 -BF Slot 2 

CO -FF Slot 3 

5.12K 12 8 K 
512K 32K 

When a Z88 lias 128K or more RAM it becomes an 
expanded machine. 

Below are the differences between an expanded and 
unexpanded machine. 


Expanded Unexpanded 

Size of BASIC 
Max Map Width 
User Chars 
Value of EOF 


256 pixels 




80 pixels 



Putting RAM in Slot 2 or 3 does not expand the machine 
(only 8K for BASIC) but does increase memory size. The 
unexpanded machine can use 64 user characters, but if an 
80 pixel map is used the last 48 of these will be 
overwritten by map information when PipeDream is used. 
Reducing the map width to 64 pixels, or not using the map 
at all allows for free use of all 64 user characters. 


One key note about EPROMs that I ran across that is fairly 
important to note: when putting (blowing) flies on an 
EPROM energy consumption is actually less than when 
you are regularly using the Z88. The extra power needed 
to blow the EPROM is balanced by the fact that the screen 
is shutdown when blowing the EPROM. Most people felt 
that blowing EPROMs was a battery draining effort. 


These devices are listed in the User Manual but they are 
kind of hidden This is a good place to bring them up 

1NP.0 the keyboard 
OUT.O the screen 
ROM.0 the 128K ROM built in 
COM.0 serial port 
PRT.O serial port (output only) 
NUL..0 unknown 
To see the list of all devices on the Z88 (including 
additional RAM), in Filer select Catalogue Files and give a 
file name of :*/ . Use a file name of :ROM.0//* to see 
what appears to be a list of Z88 applications. Even though 
the use of :NUL.O is unknown, I'll guess that it is similar 
in usage to the Unix device known as /dev/null. /dev/null 
is a device to send all your unwanted output to the 
proverbial bit bucket. If a program provides output that 
you don't need, you can redirect it to /dev/null and it will 
never appear. 

ZS8 Internals 

If you were to open up your Z88 (don't do tins lightly), 
here is what you would see: 

There are four chips in the Z88. From left to right 
they are: 

tint m;m - 32kram 

IJLA - Uncommitted Logic Array. Tins chip is a specially 
made chip for the Z88. It replaces a number of stock 
chips. Sinclair/Canibridge is known for having ULA chips 
in virtually every computer. 

Z80 CPU - This is a CMOS version for the Z88 that uses 
less power than a regular Z80 

Next to the ROM chip is the Supercap Capacitor. This is 
the power reservoir when changing the batteries. Below 
the expansion port is the speaker (see the small ring of 
holes on the back of the computer). Next to the ULA are 
the two eight-way keyboard connectors into which go the 

ZXir QLive Alive! 


Spring 2002 

ribbon cables from the keyboard. Unlike the membrane 
keyboard of the Spectrum, ZX81 and the QL, the plastic 
molded keyboard actually conducts electricity and makes 
the electrical connection. Below the keyboard connectors 
are the two crystals used for timing. 

AC Power Supply 

The Z88 lias a plug-in for an external AC adapter. When 
the adapter is plugged in, power is taken from it and not 
the batteries. 

Hie specifications for the adapter are: 

6 Volts DC 

300 - 500 milliamps 

Positive center 
Most Radio Shack stores or other electronic 
stores should carry such an adapter. The one that I 
use is a universal adapter. It lets me switch the 
voltage and the polarity. It also has 4 different plugs. 
Radio Shack has two adapters that will work with the 
Z88. The Universal AC adapter ( #23-1635HT ) 
plugs into an AC wall outlet. The Universal DC 
adapter ( #270-1 5 60HT ) fits into your car lighter 
socket and allows }^ou to externally power your Z88 
while you ride in a car ( I don't recommend doing 
much with the Z88 while you drive :-) ). If you need 
the DC adapter to reach further there is a 10 ft 
12VDC extension cord (#270-1 5 36HT). Even with 
the car turned off. the Z88 should not be too much of 
a dram on the car battery . 


Some have suggested using rechargeable batteries in the 
Z88. The standard NiCad batteries do not put out enough 
imiph to keep the Z88 up and going for too long 

One partial solution was to use 2 regular AA batteries 
and three special 1/2 AA rechargeable batteries from 
Sanyo. They would put out a total of 6.2 Volts, just over 
me 6 volts of new batteries. Some adapters are needed to 
make the l A AA batteries fit into a recharger. Spacers with 
90 Ohm resistors were made to fit batteries into the 
recharger. This is detailed in the first issue of PipeLine, 
the Z88 magazine put out for a short time by Tim Woods. 

There is a new type of rechargable alkaline battery 
available called RayOvac Renewal. These are real alkaline 
batteries that can be fully charged up to 25 times. They 
will give you the full power you need, better than NiCad 
batteries. I've never used them, but I'm sure they are more 
cost effective than buying new batteries all the time. 

The external AC adapter port on the Z88 is designed 
to take 6 volts, just like it gets from die 4 AA batteries. 
This means that almost any 6 volt power source could be 
hooked up to the Z88. Tins includes such sources as a 6 
volt Gel Cell, a pack of 4 1.5 volt D cells (see next 
section), or even a solar cell that generates 6 volts. The 
electrically inclined can work up almost any device. 

Z§8 External Cattery 


As mentioned above, an external battery pack can be made 

for the Z88. I have built such a pack using 4 D cells. I 
could have used a large rechargeable 6 volt cell, but I 
wanted to keep to using standard batteries. To get the 6 
volts for the Z88, all I needed was 4 1.5 volt batteries. 
Most standard batteries (A, AA, C, D) are 1.5 volts. I went 
with D cells because they were about the biggest I could 
get and did not cost that much more than C cells. 

After looking at various electronic surplus places, I 
found that good old Radio Shack had exactly what I 
needed. Basically I needed a batter)- holder, a box to keep 
it in, and an adapter plug to fit the Z88 . Below is the parts 
list for this project: 

270-627 Experimenter Box (6.25 , x3.75"x2") 

270-396 D Battery Holder (6 Volt) 

274-1569A Coaxial DC Power Plug (male) 5.5mm OD 

2 Lead wire (same gauge as on an AC adapter) 

3/8" thick Foam Rubber 

4 Screws 

4 Rubber Feet 

The battery holder does not fit square in the box it fits 
in at a slight angle. The box is plastic with a metal cover. 
I wanted to call the metal cover the bottom. Since it would 
be easier to mount the plastic battery holder on the plastic 
box than the metal plate, I mounted the battery holder 
upside down in the box with plastic model cement (use 

To let the lead wires out , I drilled a small hole near 
the top of one end of the box. (Since I put this all together 
upside down, it looked like I drilled near the bottom of the 

The two wires coming from the batten- holder are not 
long enough to reach out of the box, so I ran the other wire 
into the box and attached it to the battery wires. To make 
a good connection I twisted the wires together, put some 
solder on the joint, and wrapped them with electrical tape. 
To keep the wire from being pulled out of the case, I 
wrapped some electrical tape on the 2 lead wire so it would 
not allow the wire to be pulled through the hole. 

The length of the lead coming from the box to the 
plug can be as long as you want. I went with a fairly long 
lead about 20 inches. I connected the plug to the other end 
of the 2 lead wire. The Z88 requires that the inner part of 
the plug is positive ( be sure to get tins right or you might 
blow your Z88 ). It would be useful to use 2 lead wire 
with one lead marked ( usually with a painted stripe down 
it's length ). The positive lead coining from the battery 
holder is the red one. I soldered the wires on and then ran 
some electrical tape around between the two connecting 
points. I wanted to make sure that I did not get a short in 
the system. 

Once I had tins all hooked up I put the batteries in the 
holder and, using a multimeter, checked to make sure that I 
was getting 6 wits on the plug. Since the batteries were 
fresh, I was actually getting about 6.5 volts. 

I did not want the batteries to fall out, especially 
since they were going to be hanging upside down, so I put 
in some foam rubber to support the batteries and the 
battery holder. I did not glue the rubber to the metal cover, 
since some glue will eat foam rubber, plus I did not feel a 
need to have the rubber mounted. 

The screws stock out beyond the cover and would 

ZXir QLive Alive! 


Spring 2002 

scratch a table surface, so I got some stick-on rubber feet 
to prevent this . The metal cover is fairly tight and fits the 
box well. To make it easier to get the lid off 1 created a 
small notch in the cover with a metal file. I did it just big 
enough to get mv fingernail in and be able to prv the cover 

cells, I'm not too sure. I do know it will be far more 
economical than using lots of AA's. 

Lantern Catteries 

I've found two different types of 6 Volt lantern batteries. 
The first is a square batten-' about 1.5 inches per side and 
about 2.5 inches tall. The second is about the same height 
as the first but about 3.5 inches wide ( like a tall brick). 
These batteries have either little springs or metal poles for 
the positive or negative leads. 

Since they are 6 Volt, they are perfect: for the Z88. 
What is needed to hook them to the Z88 is: 
DC Power Plug (same as mentioned above) 
2 lead wire (same as mentioned above) 
Micro Alligator Clips 

Solder the DC power plug to the wire the same as 
above. Then solder the micro alligator clips to the wire. 
Be sure to mark which wire is positive and negative. You 
can buy color coded alligator clamps, but I prefer to mark 
each wire with some tape and the + and - symbol. This 
way I don't have to remember that the red lead is positive 
(or is that negative?). Now just hook the clamps to the 
battery and plug into the Z88. I have no idea of how many 
hours you will get out of either battery (I'm guessing its 
lot's). If you can't find these batteries, try a local 
campmg/outdoor store. Thev should have them. 



After having the Z88 a short time, you will probably 
notice that the keyboard seems to attract dust like a 
magnet It's not easy to keep clean. I've heard some 
discussions on how best to clean it. 

Some have suggested using a Q-tip and plain water. I 
like to use a Q-tip and rubbing alcohol. Others have 
suggested using a vinyl protectorant like Son-Of-A-Gun or 
Armor All. I don't know how these will affect the 
keyboard, so use at your own risk. 

Just don't plan on keeping the keyboard clean 
always. Just a few days after I cleaned mine, it looked like 
I had never cleaned it 

As for the screen, ideas range from blowing on it, 
using compressed air, using tissue, and using the same 
stuff you use to clean a pair of glasses. I find a tissue and 
some clean water to be good enough. 

There was mention of how sunlight affects the Z88. 
It seems that sunlight heats up the screen and takes more 
power to make the letters dark. Just blocking the screen 
from direct sunlight should fix this. 

I have no concrete numbers on the temperature range 
that the Z88 can handle, but I would guess that it should 
not be allowed to get too hot or too cold. Leaving it in 
direct sun in a parked car is a definite no-no. I have read 
that letting a LCD panel get below freezing causes bubbles 
in the panel and permanently damages the panel. Don't 

Total cost for the project (not including batteries and 
wire) was under 7 dollars. Since I took my time to get 
evenlhing right, it took me about 1 hour to build the 
battery box. 

Exactly how many hours I will get out of the 4 D 

leave your Z88 in the car overnight in the dead of winter. 
If the keyboard seems a bit sluggish or non-responsive, it 
could be the fault of the membrane beneath the keyboard 
being dirty Hie entire rubber keyboard can be taken off 
and cleaned underneath. Do this at your own risk and 
don't do it during any warranty period. 

The Z88 has been known to crash when having a 
constant pressure on it's keyboard for a long time while it 
is turned off. I've only experienced this with a Z88 that 
had other problems, but not my current Z88 (I have not 
tested it). I've picked up a "Topper' to prevent this from 
happening (see products below). The "Topper" is a plastic 
cover that fits over the Z88 and protects the keyboard and 

Of course, one of the biggest no-no's with the Z88 is 
dropping it. I do not know how much shock the Z88 is 
designed to take, but I doubt it is very much. Hie screen 
would probably be the first item to be damaged. LCD 
screens are fairly fragile and do not take well to being 
dropped. The motherboard can probably take a fair 
amount of shock. The biggest worry about the 
motherboard would be a drop on the edge of the Z88. This 
might cause some fair amount of cracking in the case and 


I carry my Z88 as part of my briefcase. With it I 
carry a few extra items. 

Batteries: Since it's hard to tell when the batteries 
will go out on me, I like to keep a set of fresh batteries 
around. It is nice to know that I can quickly pick up more 
batteries if I have to. In reading one book on laptops, one 
contributor mentioned that traveling with a laptop that 
used off-the-shelf batteries was better than traveling with a 
laptop with rechargeable batteries. Most off-the-shelf 
batteries are available almost anywhere in the world. With 
rechargeable batteries, you need to have a converter to 
plug the charger into the local electrical system (which can 
be quite odd in some countries). 

External Battery Pack: Since I sometimes use my 
modem with the Z88, I often find places where there is 
room to plug in the modem and a lamp, but not the Z88 
AC adapter. The external battery pack is great for this. It 
is also good to run the Z88 almost anywhere for extended 
periods of time. 

AC Adapter. Since I want to make the batteries last 
as long as possible, I like to use the AC adapter when I 
can. Especially if I am using the serial port, as this is one 
of the major power drains for the Z88. 
Cables: I always carry a Z88-PC cable so that I can 
transfer any documents to/from the Z88 and my PC at 
work. I never know if I have to use ray Z88 to keep 
meeting notes. Sometimes I carry a serial printer cable just 
in case I need to use a printer while on the road. 

To keep the cables wrapped up fairly small I needed 

ZXxr QLive Alive!

some cable ties that were reusable. Most cable ties are for 
single use only so they were out. I made my own cable 
ties by sewing two pieces of Velcro together, hook on one 
side and pile on the other. When used, the inside pile will 
grip the outside hook (or vice versa). My wife's sewing 
machine could not handle the thick thread and the tough 
Velcro, so I had to do the sewing by hand. With a little 
patience I was able to make enough cable ties. 

ProComm: Since most places have PCs, I like to 
cany 7 a copy of ProComm on 5 l A and 3 Vi disks. With the 
cable and software, I have all that I need to transfer 

Modem: I use the modem to dial into my Unix system at 
work with my Z88 so I can read my mail while I'm on the 

Printer: I have an older Diconix Inkjet printer that 
works with the Z88. Once I get it repaired I plan to carry it 
with the Z88. 

Here are some other items to take into consideration 
when traveling with the Z88: 

❖ Theft of theZ88. The main reason I bought the Z88 
was because of it's size and weight This also means that 
it can be stolen fairly easily. Don't leave your Z88 just 
lying around. Besides the physical theft, having your Z88 
stolen means that your files go with it, too. You no longer 
have access to those files, which can be critical if they 
were important to you. It also means that the thief now has 
your files. I doubt anyone will be keeping state secrets on 
a Z88, but this is something to consider. 

❖ Lighting. Since the Z88 has no baeklit screen you 
will need a light source wherever you use the Z88. Buying 
a laptop light will solve tins problem. 

❖ Airport Security. I keep my Z88 in my brief case 
when I pass it through airport security. So far no one has 
asked if I was carrying a laptop. When traveling with 
another laptop, I was asked to turn it on so they could see 
that it worked and was not a bomb. Just because I was not 
asked to turn my Z88 on, don't expect to be so lucky. Be 
ready to take it out and turn it on. There is also the worry 
about the X-rays from the seamier zapping the Z88. I've 
heard from a lot of people that the X-rays are fairly 
harmless. Your biggest worry is the motors driving the 
belt in the scanner. But, if you are concerned, take out 
your Z88 and ask for a hand laptop check. Airport security 
should be used to this. 

I I Vlt I S 

If you are taking your Z88 on the road, it would be nice to 
also have a printer and/or modem. There are a number of 
portable printers and modems on the market that are 
designed to work with any laptop with a serial device. 
There are a couple of good magazines devoted to laptop 
users, like Portable Office and Mobile Computing, and 
cany ads for a lot of portable printers and modems . Check 
your local newsstand or library. 


Most portable printers are battery powered and can be used 
anywhere. The only one that I've used is the Kodak 

Diconix ink jet printer. It's printer quality is just a bit 
better than normal dot matrix. Most portable printers will 
be of the ink jet type. 

For serial printers, a Z88 cable can be made or 
bought for the Z88 (see the pinouts listed earlier). For 
parallel printers a serial to parallel cable can also be 
bought. For QL users, the Miracle Serial to Parallel 
adapter will also work with the Z88. This adapter is 
designed to work on either SER1 or SER2 of the QL. 
Luckily it also works just fine on the Z88. Since 1 already 
had this adapter for my QL, I was really happy that it 
worked with the Z88. One less cable to buy. 

If you don't want to carry a portable printer or can't 
afford one, then there are ways to be able to print while on 
the road Carry a serial to parallel cable and a regular 
serial (9-25 pin) cable so that you can print to almost any 
printer. If you are staying in a hotel, ask them if they have 
a printer you can use. You could also carry cables to 
download the file to a PC and then print out. There are a 
number of commercial services that offer short tenn rental 
of computers and printers. MailBox Etc. and Kinko's 
usually have self-service computers and printers. Other 
copier places might have them. 


There are a variety of modems called "pocket" modems. 
These are modems that plug directly to the serial port and 
are powered by a 9-volt batten 7 . I have even heard of one 
that uses the power from the phone lines. Hooking one of 
these to the Z88 will require a small adapter cable but this 
need not be too long. There are even some battery 
powered FAX/modems available. Make sure that you get 
a plain text Fax modem. Most fax modems require input 
data be in the form of a CCITT Fax 3 image format. Some 
fax modems will take plain text, convert it to Fax 3 image 
format and send it. Check any of the more popular 
computer magazines for more info on small modems. 

Using your modem on the road is getting easier. 
Some hotel rooms have data jacks built into the phones. 
For those that don't, the phones are on RJ-1 1 jacks, instead 
of being hard wired into the wall. Beware that the phone 
jacks might be in an out of the way place, like behind the 
headboard of the bed. Be sure to cany some length of 
phone wire and a female-female connector so you can 
hook together two phone hues. Pay phones are starting to 
have data jacks in them. The newer credit card-only 
phones should have data jacks. Don't expect the phone in 
the phone booth to have data jacks. If you plan to use 
these type of phones, there are some acoustic handsets 
available that end in an PJ-1 1 jack. 

In some of the "standard" laptop magazines I've read 
some discussion about hooking up modems to digital 
phone lines and how they can destroy your modem. When 
talking about digital phone lines, the topic of PBXs comes 
up. I don't know the specifics of digital phone lines and 
exactly why the would zap your modem, but there are a 
few products on the market that plug into the phone jacks 
to confirm that they are in fact non-digital and are safe for 
your modem. These devices are not cheap, so you may 
want to research it fiirther before buying one of them.

What Alienates the TS-2068 


(The jjjtandard £ell Logic JJevice has not been available for years) 

Bv Victor M.S. Acuha - Buenos Aires 

Some words about myself. I was a student at CIE (Cleveland Institute of Electronics), in Electronics 
Engineering course. I worked since 1 986 in the computers field, and really I am an expert in repairing TSs. 

The topics I send in this letter are about repairing of SCLD IC. Evidently the troubles generator in the TSs 
is the SCLD IC. In the service shop I encountered about 60% of TS's failures were over it, and like it change 
cost about $30. ( I have many of them, and I did a special iron to remove them), when the price of the machine 
began to fall, an option was to design circuits specifically to repair parts of it. Now a working TS-2068 cost 
around $50. The TS repair market, practically doesn't exist. The total number of machines imported to my 
country was around 5,000. 

Principally, the SCLD problems are: 

A. No Interrupts (every -17 ms.) from SCLD to CPU and then failure. No keyboard 

B. One or more rows of keyboard do not work. SCLD does not read or its data lines are open . 

C. No cassette. Does not read data from the cassette player. 

D. The refresh circuit built into the SCLD for the high memory bank ( 32, 768-85, 535 ) A7R doesn't work. 
The machine initializes, but the programs crashes. This is the most destructive failure, and commonly only 
reparable by changing the SCLD. Yes, it is my great discovery ! ! Thanks, thanks, .. 

Keyboard Problem 

A) The SCLD provides via INT (Pin 16 Z80) signal that is necessary to scan the keyboard. This signal is 
generated in every field of the screen (l/60 th sec). But if it isn't, the CPU never read the keyboard. More 
explanations about it are in the Technical Manual. Originally, I tested taking the signal from the vertical synch, 
but it doesn't work well. Then I designed a circuit from a 555 timer, and it worked O. K . The circuit is: 


47 nF 

outfit v<p)d 

H \ 

To pm 16 CfV 

One Or More Keys Do Not Work 

B) If the keyboard fails only in some rows, and one is sure that the problem is in the data lines, (via 
oscilloscope level test, for example) and not in the keys itself, then the solution is to build a circuit that overlaps 
the SCLD keyboard circuit. The keyboard uses DO to D4 to scan the KB0 to KB4 lines, in the port 254 . This 
corresponds to AO = 0 . Then the circuit is:

Will not Read the Cassette Recorder 

C) The cassette input view from CPU is the same port as the keyboard, but in the D6 bit. All we need to do, is 
amplify the audio input, decode the 254 ports and couple it to D6 . Then the "dead" cassette comes to work.

EXTRA: Like some TSs are more deaf than others, and in general all are "hard" to hear (Sure, I designed, 
sold, and made money with a signal improver, LG-02). In the cassette input Timex put only two diodes to 
ground CR25/26 (I don't know why, only two), for bias the input of SCLD circuit, to protect the input 
electronics, and to conform the input signal. The solution I encountered was to add one diode in series between 
them. Commonly I de-soldered one end of one diode and add one more between it and the hole in the board- 
remember in the same polarity direction. Conclusion: with the three diodes my TS became an excellent machine.

D) The refresh problem was hard to find in the beginning, but with an oscilloscope and understanding of 
memory and Z80 devices, finally I win. The TMS 4416 was a new chip when it was used in the design of the 
TS-2068. And has been the Z80 best 8 bits micro, than it has inside, the refresh counter necessary to maintain 
the data in the dynamic memories, the combination was perfect. But when it was designed, only seven bits 
w ere used for this counter . It is O.K. for 41 16, 4164 family (it needs only seven bits to refresh all cells), but in 
the "new" 4416 family eight bit was needed. In the low f memory block, constantly reading to form the video, it 
makes the necessary refresh reading. But in the high memory block the SCLD makes the eight bit necessary for 
a complete refresh cycle (the A7R). When it fails, the machine can't maintain its data integrity^ and crashes. 

The first thing to do is to confirm that the problem is this, I made a little program that displays this problem 
in the form of lost UDG data, simply making ail bits set in UDG, the lost information are seen like white dots 
inside them. 

First input this program line: 


(all letters in UDG mode) 

Then input this command line: 

FOR A = UDG "A" TO UDG "U" : POKE A, 255: NEXT A 


Now all letters must be black boxes, and in the upper left side of the screen, you can see a coarse black line, 
2 1 characters long. Every time you type RUN and ENTER you refresh the display area, taking the UDG 
information from its original address ( high memory block). Running a program every minute if you can see 
how- the white spots start to appear, your machine has the refresh problem . 
Second build and install the next circuit:

The circuits given represent hours of high tech research, they are copyrighted to my mind. I send them to you 
for a help in your troubles, (and for my TS's USA folks, of course). You should not use them commercially 
without my acceptance except for repairs.

The QL Hacker's Journal (QHJ) is published by Tim 
Swenson as a service to the QL Community.. The 
QHJ is freely distributable. Past issues are available 
on disk, via e-mail, or via the Anon-FTP sender. The QHJ is always on tlie look out 
for article submissions.

Editor's Fom 

hi the- second time in the life of the QHJ. 1 have 

Hp allowed a whole year to go between issues. 

When I started the QHJ 10 years ago. I knew 
something like this might happen, therefore I made 
the QHJ a free publication. This has kept any off 
any outside pressure to get the next issue out. I 
really only have to deal with my own pressure, i 
think we all have cycles of dedication to projects 
Sometimes when we start a. project we can't put it 
clown, other times we can't, pick it up. For the last 
vear 1 really have not had the drive to do some 
programming. Other tasks have filled my time and 
interest. Even with some forced time off from work 
(yea. I'm one of the victims of the failed new 
economy), I have not really spent time doing 
programming work , 

""^jUt, I have found the time to brush off an old 
dssue that I've been working on for almost 9 
'montlis, I took the time to sit dow n and finish 
it This issue focuses on freeware release of 
TURBO, the SuperBasic compiler. Pve been 
involved with the release by editing the manuals for 
both TURBO and the TURBO Toolkit. 
^Remembering hearing about the possible re- 
ffiKreleasc of TURBO in QL Today back in early 
i 12000. At the QL 2000 show in October 2000, 1 
happened to run across George Gwilt. 1 asked him 
about TURBO and hinted that I'd like to get a copy, 
if possible. Soon I had TURBO and George's 
Pointer Environment TURBO Kit. TurboPTR. Not 
being a previous TURBO user, I needed a manual to 
figure out how to use it. 
pik imon Goodwin send me his original manuals, 
kwhich I edited to reflect the new TURBO.. I 
'plan to use TURBO for ail my programming 
projects. I'm hoping that a totalh freeware 

SuperBasic development package (TURBO, 
TURBO 'Toolkit, TURBO Config, and TurboPTR) 
will encourage a more QLer's to start programming 
(kind of like what C68 did for C programming on 
the QL). As of this issue, I plan to make the QHJ an 
electronic only publication and sent out a prist copy. 
This pretty much only affects the US readers, as I 
sent very few issues outside the US. I believe that 
most readers have a way to access the QHJ via web 
or e-mail 

Turbo Compiler 

£g*JURBO, the SuperBasic compiler, lias been 
updated and released for almost a year Simon 
Goodwin is the original author with a few 
others contributing to the final released product, by 
Digital Precision, George Gwilt has taken the 
source code and updated the program to work on the 
newer QBOS and SMSQ/E systems 
TURBO comes in the following packages: 

- TURBO Toolkit 3 3! 
-TURBO 4.10 

- TURBO and TURBO ToolKit manuals 

- TUR BO Config 

- TurboPTR 

- TURBO Utilities 

- Task Commander 
URBO Toolkit (TTK) has been updated by 
Mark Kniaht and must be loaded for TURBO 
to am. The manuals for TURBO and TURBO 

Toolkit, have been updated to reflect the new 
versions. TURBO 'Config and TurboPTR are new- 
tools written by George Gwilt. TURBO Utilities is a 
collection of tools for use with TURBO compiled 
programs Task Commander is a tool that allows a 
TURBO compiled program to become a 

ike Qliberator, TURBO compiles off a program 
^already loaded into SuperBasic, Unlike Qlib, a 
work file does not need to be created first. 

TURBO is comprised of two parts, the parser and 
the code generator. The> are two separate 
executables, but are linked when using the 
CHARGE TTK keyword. The parser has the main 
user interface to TURBO, In the parser the user can 
change various compile options, including 
where the destination executable will go and the 
runtime name of the executable (as displayed by trie 
JOBS command).. 

ZXirQLive Alive! 


Spring 2002 

lot of the compile options can be set within die 
iSuperBasic program itself, using TTK keywords 

starting with T 


TURBO_ buffersz, TURBO_ob jfil and 

TURBO repfii Other commands like IMPLICIT! 
and IMPLICIT 0 /*, inform TURBO how to treat 
variables. IMPLICIT 0 /*, varl, var2* tells TURBO to 
treat these variables as integer variables (varl%, 
var2%). By default, SuperBasic variables are treated 
as floating point, but TURBO knows that most 
variables do not need to be floating point and that 
most programmers do not take the time to use the 
percent sign in their programs. The IMPLICIT% 
allows the programmer to continue to not use the 
percent sign, but tells 'TURBO to handle the variable 
as an integer, thereby saving space (integers are 
smaller than floats) and runtime. 

Major Differences with QHb 

*! - Ho Linking &§ Extensions (Toolkits) 

TURBO does not support the linking of SuperBasic 
extensions into an executable. With QHb, the 
extension can be linked and become part of the 
executable. The major reason for doing this is to 
include commercial extensions (like Qmenu, and 
QPTR), into an executable without having to 
distribute the extension separately. If an extension 
has to be distributed separately, then a license fee is 
usually required by the owner of the extension. 
|dt is also done not to require that an extension is 
i loaded before the executable is run. If you have 
Ian extension that you think the user will rarely 
use and not want to install, linking into the 
executable it transparent to the user. 

hie downside is that if the extension gets 


then ine older version will si 

in the 

executable. Keeping the extension out of the 

executable will allow the extension to be updated 
and not require a recompile. Some older QL 
programs are rendered inoperable due to an older- 

extension clashing with SMSQ/E. 

2 - Fussier about SuperBasic 

Qlib can compile almost any SuperBasic that would 
run on the QL. TURBO is fussier about what 
SuperBasic code it will, compile. 
An example is how file names are used. In 
SuperBasic a file name does not need to have quotes 
around it. In TURBO, they are needed. 

Qlib - open #3 .win I _fi!e ext 

TURBO - open #3>inl _"file_cxt' 
Plus TURBO has a number of keywords (from 
TURBO Toolkit) that help TURBO know more 
about the application. They have a tendency to give 
the program a more TURBO feel With Qlib, any 
compiler directives are put in REMark statements 

and not using keywords 

3 - Sxesiitalsle Speed 

fhc major benefit that TURBO has over Qlib, is 
that resultant executable is faster than one 
compiled by Qlib,. I had no first hand 
knowledge of this difference so I decided to compile 
a program with both Qlib and TURBO and compile 
the time it took to run the program For the test 1 
used the Ratciiff/Obersheip Pattern Matching 
algorithm as listed in QHJ # I . The main function is 
percent alike() The program I wrote called the 
function 1000 times, using the arguments of 
Pennsylvania and Penciivania. Since I was using a 
Q40 as a test machine, I needed the program to run 
long enough to give me some meaningful numbers. 
1000 times turned out to be long enough, 
jre is a table of the results: 
SBASIC 12 sees. 
Qlib 8 sees. 

TURBO 5 sees.

rand gt com 

in general, using TURBO takes a little more work 
than using Qliberator Both can compile simple 
I programs witliout any changes, TURBO gives 
the programmer a little more control over the end 
product with a variety of commands that control how 
the executable is compiled.. The end result is that 
TURBO is more powerful than Qliberator, but. the 
power comes at the price of needing to know more 
about TURBO to get to that power. 

TURBO manuals do a pretty good job of 
documenting TURBO and the use of the 
various TURBO Toolkit commands. In some 
places it does go into a little too much detail for the 
average programmer 

Converting from Qlib to TURBO can take time and 

be a little painful . for some there may not be a need 
to convert over, as QLib may be working just fine 
for them. But as TURBO keeps being updated the 
Qlib user may hit a problem with Qlib on newer 
platforms. Plus, I think there is an advantage to 
using a freeware compiler. 

Turbo Conflg 

y^lURBO does not support standard Qjump 
Config Blocks. George Gwilt has 
created TURBO Config, a tool that allows 
Config blocks to be added to 

TURBO compiled programs After creating some 
data statements that get merged with the source 
code, another tool takes the Config block 
information and adds it to the compiled program. 
T CONFIG_DATA is the program that takes your 
Config bock definition and creates two files. The 
first is the data statements with dummy data, holders. 
The second file is the actual data that, will be put into 
the Config block. T CONFIG_LOAD is the 
program that takes the Config block data and puts it 
into the compiled program. 
The process goes something like this : 
8 Write your program, 

■ Use T CONFIG _D ATA to create the DATA 
statements and to define the data, 

■ Merge the DATA statements with your 

38 Compile the program. 

» Use T CONFIG. JLO AD to load the Config 

block data into the executable, 

(he Config block data is read by using READ 
statements and selecting the right item by 
using RESTORE statements. Due to the way 
strings are stored, they must be read twice, with the 
second read getting the real string. Below is an

extensions, esp, those with array parameters or 
return values through parameters, QPTR is 
one such set of extensions. So, to create Pointer 
Environment programs using TURBO. George 
Gwiit has written TurboPTR. which is a freeware 
replacement to QPTR. 

(urboPTR is comprised of the following 
TPTR - a set of extensions 

TPTRJBAS - a set of SuperBasic routines 

that get merged with your program, 
TPIR.___SETF.TASK - a program that helps setup the 
window definitions (inc. sprites and such). 
TurboPRT also comes with some example sprites 
and three examples programs 
I'm not a PE programmer so I can't say much about 
TurboPTR other than I hope to find the time to try it 

Task Commander 

fesk Commander is a utility that will convert a 
TURBO compiled program into a resident 
extension or Toolkit, that can be RESPRed 
and seen as a new keyword in SuperBacis. 
Task Commander will produce a keyword that will 


produce the same citect 

Commander is not designed tor creating iibrarj 
extension with many keywords. The program is 
fairly simple and only does this one thing. 
Documentation comes with the program that quickly 
explains how to use the program and even how it 

Turbo Utilities 

nother zip file contains a number of other 
iDATASPACE and UtiiitvTask 
The zip file does not come with documentation, and 
briefly explains the programs: 

LIBRARY MANAGER - pulls out procedures 
from large SuperBasic programs. 

DATASPACE - used to adjust the data space 
requirements in programs already compiled.. 

Utility task - Neat little utility program that does 
three things: 

Charager Graphics Editor, Sound Effects Editor, and 
Toolkit Default Editor, 

Turbo Sypport Page 

$o assist in the support of TURBO., Fve created 
a TURBO Support Page on my web page 
The page will list the various reported bugs to 
both TURBO* and TURBO Toolkit Each bug will 
list what it is, what platform the bug has been seen 
on (QDOS, SMSQ/E, etc), and the status of work on. 
the bug. Using this page should take some work off 
of George Gwiit and leave him to concentrate on 
actually fixing bugs.
