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... http://www.smrcc.org.uk/members/g4ugm/acc.htm Dave > > 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.
