I agree that the x86 ISA is pretty warty (though I have a strange fondness for it), but I'd recommend 6502 rather than Z80. There are a lot of fun retro-computer platforms that are 6502-based. Thinking of the zero-page functioning as a register-bank is really fun, too.
- spc476 10y agoFor 8-bits I'd recommend the 6809. Two 8-bit accumulators that can be used as a 16-bit accumulator, 4 16-bit index registers (that can largely be interchanged, except for S which is also the stack register) and you can generate pure relocatable code. And the zero-page isn't restricted to address $0000.
- qwertyuiop924 10y agoYeah, but those are hard to get.
- EvanAnderson 10y agoThis sounds really interesting. I've never taken a look at the 6809 before. I happen to have a working Tandy CoCo I scored in a vintage computer haul. I'll definitely check out 6809 assembler.
- qwertyuiop924 10y agoI know that asxxxx will assemble for the 6809, if you need an assembler.
