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!
