In 1983 at the end of taking a digital tech course at a community college here in Toronto at George Brown CC, I spent about a month assembling and debugging a trainer kit that my prof was marketing, similar but more sophisticated than the Heathkit ET34400. It was called a M(icro)SOKit 68. It was based , of course, like the ET3400 on the M6800 CPU. Does anyone have one of these out there ? It was geared to teach students about micros by building their own micro. I know he sold a number of them, but don't know how many. I have the manual, parts #s, etc. if anyone is interested. Included in the manual is a couple of pages of layouts obviously meant to be photocopied and etched. ciao larry lwalker(a)interlog.com
