This goes back to the old Timex/Sinclair/TRS-80/Coco/CPM systems.
This is a work in continous progress.
I'll try to keep at it, but I do have time limits.
Old Computers
- This list includes many sites for info on old 8 bit systems, mostly
Z-80 based, and mostly Tandy and, above all, mostly TRS-80. Some overlap,
and some have the same name but those are not duplicates.
Also, there is a TRS-80 maillist, a Tandy Usenet group, and a TRS-80 Fidonet
echo.
For those not familiar with it, the Fidonet is a BBS, (Bulletin Board)
based network, sorta like an amatuer version of Usenet. The big difference
is, the Fidonet is much more regulated as to behavior and topicality. Each
group, known as an "Echo", has < BR> a moderator who has
real and enforcable authority to boot abusers off. This is possible because
the system is based on local bulletin boards, and runs through gateways
and nodes. All of these are points at which the unco-operative can be cut
off.
The Trs-80 echo, TRSMOD-134 is inhabited by a friendly group of devotees
to the old systems. Few actually use them for daily use, but many still
like to play with them, or with the emulators available for PCs.
To join, check with a local BBS. If you don't know of one locally, contact
the local Radio Shack store, or local computer clubs.
I am the moderator of the Trs-80 echo, and welcome all who are interested
in the systems and conduct themselves responsibly.

The model 1 is the computer that got me started. I had several, plus several
model 3s, and a couple clones.
Early on I wrote my own checkbook program, and my own Hurkle program. If
you don't remember the Hurkle, well, don't be surprised. It was an early,
and primitive, number game.
Mostly I was a hardware hacker. I came up with my own modifications for
double clock speed, lower case, put 48K ram in the keyboard, replaced the
roms with ram, put 2K ram in the keyboard area, and a couple extra key
mods.
With the ram replacing the roms I modified the operating system to do things
like start loading a tape (remember those) in the middle of a program without
bombing, look for the name of a basic program, protect video lines from
scrolling, run faster, a bi
t anyway, and I don't even recall what else. I actually burned a set of
roms running that system, but the computer is long gone and I have no idea
where it is now.

Once the most popular computer in the world.
Still a marvel of simplicity.
I've had several. Still have for that matter, mostly closet computers now.
If, however, anyone has some books on machine language for the Timex/ZX-81
I would be interested. I still have a few ideas I want to work on.

coco
- I bought a Coco II only because 73 Amateur Radio magazine published
an article on using one for slow scan TV. Until then I saw no reason to
change from my Model 1 or Model 3. I had several of each.
I never did get the coco going on slow scan, but I did switch to it for
everything else. I only switched to a PC compatible because business was
running PCs, and I had to be compatible.
At that time there really wasn't that much advantage to the PC, and even
less for the home hacker.
