I've got you all beat,
the first computer I had was kit built, National sc/mp evaluation chip, had 1k ram, programmed with front panel switches called miniscamp,(1978) the second computer was a huge leap forward, the Exidy Sorcerer mark II with 16k ram, 32k rom & expanded to 64k ram later, built an interface card for a pair of 8" floppies,(1982)
wow!!
