New not working driver: mupid M-Disk
Marked as non-working because the correct terminal isn't emulated, so we can't fully verify that everything works. Run it with '-ser terminal' to see the garbled output. This also adds the clone Grundig FL-100.

mupid M-Disk Comp.-A
|
||||
Grundig FL-100
|
||||
|
||||
Floppy disk station, usually connected to a mupid C2D2/C2A2 or the
|
||||
Grundig PTC-100.
|
||||
|
||||
Everything here is guessed based on the software and a PCB image. You
|
||||
can see garbled output when you connect the builtin terminal to the
|
||||
first serial port ('ser'). It does boot from floppy too, so presumely
|
||||
only needs an emulated main system to work.
