Concrete example that happened over the weekend

No known copies of iRMX 86 on 8" floppies for the 86/380 multibus system existed, but we had copies
for a later machine on 5". The 5" files were copied to a simulation running in MAME, written out to
a simulated 8" floppy, tested against a simulation of the 86/380 (different cpu board and disk controller
than what the image was written to) then the floppy was written to physical media, given to the person
with the system, and booted up.

This happened faster than I could find all the parts to do the same thing on real hardware, and now
we have another simulated configuration working!
