All this talk of CPUs got me back onto thoughts of homebrew CPU

Check here for ideas.

So, has anyone come across a good online resource
which compares
vintage CPU instruction sets? It'd be useful to see what 'core'
instructions* were most common back in the day and use that as a basis
for my own homebrew effort; I think I can probably rustle up things
like hardware multiply and divide, but really don't want an
all-singing solution. KISS and all that. :-)
* My hands-on knowledge is pretty much limited to Z80, 6502, 68000 and
x86, and it'd be nice to go a little further back in time - but
hopefully without having to download and digest many different databooks!
cheers
