BBC floppies, Master Compacts, and a touch of Amiga

After the last BBC stream I pondered that maybe the suspect disc drive’s heads were just dirty, so we clean those.

More on the Z80 boards, the A501, and some parts salvage

Trying to get the backplane connectors into the backplane board (they’re wire wrap connectors I think, so the pins seem slightly larger)… Seeing what IC sockets I have, checking some 74 series logic chips in the Minipro, first look at the “suspect” A501 from the Amiga, and salvaging a few bits from an old PSU.
