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
HomebrewCPU.org. 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 from
Google.
Vince Briel has constructed a
replica of the Apple I; it
looks very cool!
Here's a
Circuit Cellar a
three part article which talks about building a processor and
designing an instruction set architecture:
Part I,
Part II, and
Part III.
Here's a
series of web
pages describing a bunch of electronics things.
Tomi Engdahl wrote some
great
notes on building electric circuits.
