- I have an old TRS-80 Pocket Computer (the first model Radio Shack came out
- with in about 1980). I'd love to have some information on this little gem.
- In particular, I'm wondering what processor is used and whether I can get
- directly to the CPU, bypassing the built-in BASIC interpreter. If so, I'd
- also like to know how to drive the speaker, LCD display, and output port
- (used to connect to a cassette mass storage system!). I've popped open the
- case and found several fairly large surface mount chips labelled SC43178 OJ 15,
- SC43177 OH 35, and SC43125 OG 33 (three of them). I can't find these in the
- 1991 IC Master, so I'm at a bit of a loss. Am I right in suspecting that
- the processor is some bit-slice thing?
-
- Anyway, any information you can supply would be greatly appreciated.
