I would have guessed that it's version of DOS is
customized just like all the sort-of-compatibles. But
I had thought that MS-DOS utilizes (perhaps heavily)
the programming interfaces built into the bios rom. I
could be wrong. But if that's so, I'm surprised there
was a version of DOS available for it at all. Was
there a DOS available for Multibus 8086 systems?
Regardless of the fact that it runs DOS 2.0, I think
it's a function of the bios to search for a rom
associated with a graphics controller.

I'm too lazy to do a simple search right now, but I'm
thinking all 8" drives use 1024 byte sectors. Bracing
for possible incoming *eggs*, my APC has 8" floppies,
so my guess is that they're both compatible in that
way at least. The Xerox 16/8 had as an option 8"
drives, but those I don't have with mine (it is

would handle all that though I think. If you need
particular help with something, he's very
knowledgeable. The owner of one of the more notable
vintage sites has a Gazelle Jim. You could enquire
about software from that dude. If you're too busy,
I'll do it for you. I want to see that bad-boy
running, and even if it means taking a trip up there
(with my APC) at some point, I'm willing.

I've been told recently that 8" drives can be readily
replaced with high density 1.2 meggers. Not sure if
it'll work the other way around though. I'm going to
be playing with this stuph more in the coming weeks....
