About smp
Graduated college with my BSEE in 1975. MSCS in 2002.

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.

CP/M System) and HP-9121D floppy disk drive, HP-110+ with HP-9114 floppy disk drive, HP-200LX, HP-41CL, HP Jornada 820, Apple IIC+, Apple IIGS (ROM 3), Tandy 2800HD, CoCo 3 with SDC, CoCo3FPGA, Heathkit H8, Osborne 1, Osborne Executive, Kaypro 2, Macintosh 512KE, Macintosh PowerBook 170, Macintosh Graphite iBook 466MHz (M6411), DEC PDP-11/23;
