Acorns? That brings back memories of the days as a kid I use to watch a couple of old British geisers (Brits, take no offense) fool with the Acorns on cable TV channel here int he states.
Nothing very interesting though. But here's the first computer I simply loved for the stealth look. It came CPM and had a built in assembler and disassembler, which was what I wanted to get into at the time. Z80 processor if I recall correctly. Anybody remember Memotech MTX??
