Many were not published. A friend built a TTL computer based on the PDP-8 but no details
were published.
There was a design in the UK called the "weeny-bitter" in the Amateur Computer
Club newsletters. Not sure how many got built...
Information is scattered through the magazines. I think start at volume 2...

1993 article on building a multiprocessor 6809
box.
http://www.bradrodriguez.com/papers/6809cpu.htm
Read that page years ago.I have always like the 6800 CPU model.I have used
that model for a 18 and 20 bit cpu design currently being bread boarded in
DE1 FPGA development kit,
~900 logic blocks and a few small ROM blocks.
Where are all the articles about a TTL designed computer?
Yes I know about (Homebuilt CPUs ring) but that is mostly today. What about
the Late 70's and Early 80's?
I need a the web site "C compiler for the IMPOVERISHED", I have Ron Cain's
1.0 Small C compiler modified to generate code for my architecture but the
code is really inefficient.
It is the only C compiler with source that fits in 64KB. (8080) Ben.
