Some of the fun things to do with a small micro like Mippy are well
documented at 6502.org
Bill Buzzbee has done a fabulous job of documenting his design of a
homebrew CPU at
. His processor is also a microcode design but is
register based and 8 bits wide. A Vintage Computer Fair attendee
pointed out Bill's work to me and I admire it quite a bit. Good luck,
Bill! Building a homebrew CPU is the most fun I've ever had!
I found the coolest
homebrew CPU at Mark's TTL page
. You may think it's simple, but I
think it's brilliant!
Dennis Kuschel built MyCPU
from 7400 series
TTL logic. His site is in German, here
is an English translation
Vince Briel has constructed a replica of the Apple I
looks very cool!
Here's a Circuit Cellar
three part article which talks about building a processor and
designing an instruction set architecture:
Here's a series of web
describing a bunch of electronics things.
Tomi Engdahl wrote some
on building electric circuits.
