I do, but, wait for this, on 3.5" floppies. The standard MG1 floppy drive
is an 80 cylinder 5.25" unit, and can be replaced by a '720K' 3.5" unit.
That's what the previous owner did to my machine.

AFAIK if you image-copied the 3.5" disks I have (and it's quite a number
of them) back to 80 cylinder 5.25" disks, then you'd have the standard
installation kit. Or you could pop a 3.5" drive in your machine -- If I
rememebr the schemaitcs correclty, though, you can only have one floppy
drive in there at a time.

> We have docs for them (no service manuals unfortunately) but no install

I have a manual of schematics, service notes, etc. Not sure it would
stand photocopying though, but at least the diagrams do exist.
