My first experiences with computing was with a Bendix G15 drum computer at Carnegie Mellon. More followed with CDC G20, IBM 360, Univac 1108, Apple II, and 386XXX. I have done microprocessor programming and design for 6502, Z80, and 8051. I have moved to C# now and am still struggling to understand this. My career has been in engineering starting with Texas Instruments and continuing with Becton Dickinson, Dataproducts, Hitachi Printing Solutions and now retired from Ricoh Printing Systems Europe.
