I have two Z-100's, each with dual 5 1/4" and dual 8" floppies and lotsa
memory.  I have a third Z-100 with only dual 5 1/4" floppies.  All are
running MS-DOS 2.xx, and I have the distribution disks with lots of what
I recall is BIOS source code.

A Vector-4 Z80/8088 computer with 10-megabyte hard drive and 596-kilobyte
hard-sectored floppy drive recently "fell into my lap"; and everything
seems to be in good working order.  The computer also contains an
"almost" S-100 bus (its cards don't use on-card voltage regulators).
I have been able to acquire a hardware documentation manual, too!

What I'd like to do is move the Vector disk card and both drives into my
smaller Z-100.  (I'm willing to have them external to the chassis.)
I have the hardware "smarts" to make an "almost" S-100 card into a "real"
S-100 card, assuming it can be done at all (I haven't yet really studied
the manuals), but I've never "played" with the software enough to have
any idea how to tell it when I add two more drives.

Can someone point me in the right direction on either how to proceed or
how to learn how to proceed?
