My own Joyce has the 3" drive replaced by two Teac 235F (720K)
drives. If you change a couple of bytes in the boot sector of an PCW
8256 boot disk, it'll boot just fine on an 8512 as a 720K drive.
One gotcha to look out for is the power connector on the Joyce 3"
drives--it *looks* like a standard 3.5" floppy connector, but the +5
and +12 lines are exchanged. Magic smoke time if you miss that one.
With 2 720K drives and the full complement of DRAM (512K?), the 8512
is actually a pretty decent system for general CP/M work.
