@simsa03 Wow, that's quite a project. Last time I "helped" build a what we called microcomputers back in the 8bit age was about 1978. It was based on a Z80 microprocessor. The big disk drive we got had about as much storage as...I dunno...a credit card? I was an uncle before I was a Whoopah (grandfather), but all my nieces and nephews are now in their 30s and 40s. Corrupt (enjoy) them when they're young, as the Jesuits recommend (sorta). It get more difficult and beautiful as you and they age.
