Tim Mann's TRS-80 Page:
Though he gave away his TRS-80 Model "I" long ago, he has a pile of
old Model "I" technical and hardware manuals, and a good memory. If
you have questions, he can probably answer them.

Paul Robson's Emulator Pages:
To build these you will need the shareware A86 assembler (easily
available) and a 'C' Compiler. The programs were written in
Borland's Turbo C 2.0 but should compile fairly easily under most
compilers.
