on zimmers.net there are two version of speeddos. Speeddos extends the DOS
from commodore. When all ROMs are replaced by speeddos, the DC rom is
changed, too. We know for every DOS version and drive type exists a special
DC rom. So i think it must be for speeddos, too.

The speeddos roms on zimmers.net are for matushita drives. There are for
8250LP or 8296D!

The dump speeddos-fdc-f800.bin is bad. I think i have rebuild it, so the
checksum is now correct. The other dump dos-2.7b.bin from Wolfgang GŁnther
must be a speeddos version, too. Only some bytes are changed.

In the german forum64 i found an other speeddos rom. This must be for
8050/8250 with Micropolis drives.

But now, three version are missing:
- SFD-1001 (must be the same as on zimmers.net, but support only one drive),
- 8050/8250 with MPI drives and
- 8050/8250 with Tandon drives.

Did anyone know about these speeddos versions?
