Does anyone have specs or even better original documents for a Micropolis
1015-2 (aka mod II) 5.25" floppy drive?  I have two connected to
a Micropolis designed floppy controller in an old S-100 system.
...
I wrote portions of the PROM and CP/M BIOS for this thing when I was
in highschool.  I, of course, saved many pieces of the things and am
preparing to bring one of them back online soon.

Hmm, I wonder if that's the same PROM as in my VG systems; I've
tried to replace the 1015-IIs with 1.2MB HD drives and although CP/M
is quite happy with those, the system won't boot from them, so it
looks like there's something fussy in the boot code in the Micropolis 
PROM. I don't suppose you still have any source code? I don't think
it'll be the same but it might give a clue or two...
