The question was asked (I misplaced the note) if the OS images that are on the
Xhomer website work with David Gesswein's MFM emulator on real hardware.
You can turn these into emulator data files, provided you have the latest
ext2emu tool that's part of David's software (as of 1/19/2021). The format
needed is "Elektronika_85" which is the Pro format, called that because it was
first added to the emulator as the format found on the Russian bootleg copy of
the Pro of that name.
Results, on my Pro 380:
1. P/OS 3.2: works.
2. Venix: panic at boot, "Bad access number". That doesn't mean anything to
me. I wonder if the issue is that Venix doesn't support the 380.
3. RT-11 5.3: works.
For grins I tried a smaller interleave factor than the default 5:1, since it
seems reasonable that this should make things go faster on the Pro 380, given
that its CPU is about 4x the speed of the one in the Pro 350. Somewhat to my
surprise this isn't the case; the performance indicates that at 4:1 or smaller
interleave the software misses the next sector and has to wait for another
revolution.
