My involvement with computers goes back to the end of the 1960's, when I began by working on some of the last 2nd-generation machines (junction transistors and ferrite cores: not an integrated chip in the machine). Interest in home-built computers started about the same time, but didn't come to fruition for another decade or so. Around 1978, I built Simplex-III, an 8-bit CPU built from small-scale TTL chips.
