My first computer was an COSMAC ELF based on the RCA 1802 COSMAC, one of the earliest 8-bit CMOS microprocessor. There were several of them used on the Galileo spacecraft . I wrote my own homebrew FORTH interpreter to run in its 4Kb of ram. That was a long time ago.
Since I went through a Z80 CPM machine, was project engineer for the Timex Sinclair TS1500, did the place and route of a couple of chips for the Apple II. Now working in EDA software.
I've also been interested in the TI MSP430 embedded controllers, because of the low power and analog capabilities. Created a minimal Morse code based computer, using a MSP430F2012EZ target board, a paper clip and lithium battery. I called it the IFinger. It flashes the temperature and battery voltage as in Morse code.
Bought the RPi B+ to stream audio from my stereo system, to my Android phone, but still don't have it working yet.
