Humm.... Soldering chips on a manufactured PCB (that
someone else designed)
isn't really "building your own" (although it's a step ahead of what
most people
today consider as "building a computer"). If you really want the experience,
design a system, prototype it and debug it - you will learn TONS more than you
would by soldering chips to a board. It's not nearly as hard as you might think
(start small).
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
too, on small cards,
Possibly - Although Cubix was originally designed to be the OS for my main
computer, and by that fact is pretty close to what I envisioned. It was however
done 25+ years ago, and there is room for improvement. I'd wait until some
more people have gotten into it and see what feedback develops.
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
