Graduated college with my BSEE in 1975. MSCS in 2002. Retired in October 2016, and I’m loving every moment of it. A note from my past history: In November 1976, I opened the first computer store in NH: Microcomputers, Inc. We sold IMSAI, Polymorphic, and Northstar kits, and assembled cards and computers. We attempted to sell complete systems into local small businesses. My partner and I operated until the fall of 1978, when we went broke. I have (currently working): Altair 680, IMSAI 8080 with JAIR-8080 CPU replacement running CP/M v2.2, HP-86B with HP-82900A Auxiliary Processor (A.K.A.
