about a year ago i purchased a trs-80 model 100 at a garage sale for $3. at that time i thought that it did not work. today i took it out, plugged it in, adjusted the screen resolution, and viola, something appeared on the screen! i replaced the batteries, and now it is full functional (i think), but i have no clue how to use it. it reminds me a lot of my ti-83 calculator, but a lot heavier. if anyone knows of any good programing guides for BASIC, i would like to learn how to make simple programs on this thing

edit: i did a little research and found out that this is the model with 8k of ram/rom. 8k! i think my cell phone's ringtone is larger than that!

Awesome! i loved those things. I used to have one. Try to find the floppy drive (and accompanying disk) that gives you 100KB floppy storage on a modern floppy. The floppy also runs on batteries!!!

4 AAs and you get 100KB storage.

Also, look on the web for the model100 club

 
Model 100's are awesome machines for what they're capable of. I have several here. A piece of lore behind the Model 100, btw, is that the Word Processing component of it is the last actual production code that Bill Gates personally wrote for Microsoft. In 8085 assembly language.

Some of us here collect KIM-1s, btw. Learned how to program it in high school with the hex keypad in 6502 assembly. Still have it. Works great. It's fun to have a computer that's as old I am. :D
