TI-99 Hardware Schematics





Tim Tesch recently ran accross a nice collection of TI schematics and got them into my hands. I have now scanned them and cleaned them up a bit. Most of them run about 800K or so. They are set up to print on 11 x 17 paper. If someone wishes they may post these to whtech.
