It sounds like you are building a machine similar to the EDUC-8, which was a hardwired
machine built from 96 TTL ICs and unashamedly based on the PDP-8. Here's the front cover of
Electronics Australia magazine, December 1974 showing it in front of a Straight 8 at Fairfax
publishing, Sydney. The project construction articles started a few months earlier in August,
pipped by the Mark-8 by just a month. The construction articles are still available as a small
book.
