RCA Cosmac Development System IV (CDP18S008) (ca. 1978)
(Retronics series) hELLO wORLD from Embedrock City
As far as microprocessors are concerned my roots are in the early 1980s when all sorts of ‘hobby systems’ were around based on competing devices like the Z80, 6502 and 8085. I’ve always hated electronics that gets hot while doing nothing useful so I left these NMOS current hungry micros, fan clubs and BBSs well alone and went for a less popular 8-bit number cruncher called CDP1802 originally designed and produced by RCA, the company behind the famous CD4000 series of logic ICs.
