I've got this hazy memory saying that the boot area (or possibly just the 
first track?) of the 'DD' CP/M disk might still be FM, though, even though 
the rest of the disk isn't, and so it needs a FM-capable controller to 
write out an image. Maybe I'm mixing that up with a different system, though...

I went through maybe ten different PCs here looking for one which could 
write FM, without any luck. Then I stumbled across an ISA multi-I/O card 
made by Goldstar which has an on-board FDC that *does* work, so that lives 
in an old Pentium-1 ISA/PCI AT machine with the motherboard's integrated 
FDC disabled in the BIOS.
