What did the SB use for a diskette controller and why the varying DAM's
(sometimes it's just a single sector or group of sectors on a track)?
I actually encountered a couple of those machines early on, but never did get
a hold of any service data on them. From what I heard later on, though,
they had _two_ z80 chips in there, one as the "main" processor and the other
one to handle disk i/o. Maybe that has something to do with it?
