Well since I am playing with CPLD's I need to know lot about the
insides of a computer chip.
For me I don't think I could go wire wrap as I don't think they make 84
pin plcc sockets.
Did not BYTE have somebody doing a 6809 system. They also had a nice
6502 home brew

I just want source code for a Good C Compiler. I don't think I can port
6809 asm code to my
cpu since CPLD design is something like a 6800. 6800 seems more likely.
[AC - 18/9 ] accumulator 18 or 9 bits -- bytes are unsigned
[DP/SP 18/13] direct page - sp zero filled 13..1 or stack
[IX - 18/9 ] index reg
[PC - 18 ] program counter
