DC500? That's one I've never run across.
Could be. The IBM 5100 is the first system I'm aware of that used a
DC300 tape. It wasn't serpentine and was hugely wasteful of the
tape, recording one of two tracks or the other, but not both at the
same time. FWIW, a friend with a 5100 reports that a DC600A tape
works well in his 5100 and gets more capacity.
Later DC300 drives were serpentine, for example, the early tape
drives for the PS/2 series took DC300XLP tapes. I think this was
also the case for the 6157 drive for the RT as well.
How close in construction are the DC100 and the DC1000 minicartridge?
