Quite some time back, I posted the 180-page manual for the Tandy/Radio Shack Science Fair Microcomputer Trainer Kit on my web site. It's mostly in monochrome jpeg format where each page has a clickable thumbnail. Sorry they're jpegs...I don't know what exactly I was thinking back then...

http://www.polylith.com/~brendan/ClassicComputers/Tandy/uCptrTrainManual1.html

The first page also contains a link to download the entire manual in tar.gz format.

This manual starts out with an introduction and information about how to go about wiring this spring-terminal kit and then goes on to how to use the builtin games and software. The majoirty of the manual, though, is dedicated to how to go about programming it using the hex keypad, including numerous sample programs.

I've always been intrigued by those things and their bigger brothers from Heathkit, but have as of yet resisted acquiring any. You obviously enjoy it, so I'd be interested in hearing how you've messed with it if you don't mind...

Bill, keep in mind that I was about 11 years old at the time, so about all I did with it was program it. I have some of the programs written down somewhere, which is good, because I can't for the life of me remember what those programs did! This was the first time I had ever dealt with a machine on which I could single-step through my code for debugging purposes, and it worked really well while I was learning. It seems other folks have spent more time driving simple devices from it, which would actually be quite easy by connecting them to the outputs normally connected to the LEDs. For examples, see the links below:

Terry, here's a link that has the actual processor model number (TMS1100) - I couldn't remember, so I was going to check when I got home tonight, but this is quicker:

I wouldn't mind having one of those again.... Like a moron, when I moved in 1997, I was pissed because of the sheer quantity of stuff I was moving, I ended up throwing (3) Apple IIc+'s, a franklin ace 1000, a Laser 128EX, and one of these microcomputer trainers down the garbage chute of the apartment building I was moving out of.

I've regretted it many times....no need to hammer me :confused:

Gotta add that one to my want list....
