- Last I heard, Nick Kennedy wasn't very excited about people looking at his
- source. I think that's what the documentation says. Anyway, if you
- want the source, I think you need to contact him.
-
- Disassembly is a big problem if you don't have a PC. The assembly code
- is 8088 assembly, not 6502, so the person looking to port the software to
- another platform has a real challenge. And for most programmers, the idea
- of porting an assembly language program isn't very exciting. I would
- suspect that most would find re-writing it in C would be the best bet.
- What is really needed is a list of the signals that the RS232 port needs to
- read and send, along with information on necessary delays.
