Add SpeedDOS support #689

Closed dirkwhoffmann closed 3 years ago

dirkwhoffmann commented 3 years ago

As a preparation for #684, add support for SpeedDOS. SpeedDOS is simpler, because it utilises a standard-sized 16KB Drive ROM and does not require a Drive RAM expansion.

A SpeedDOS+ clone (v2.7, TRIAD) is available here: https://csdb.dk/release/?id=21767

The next version will offer an option to attach a parallel cable to the user port. Right now, only "standard" cables are supported (DolphinDOS will require a custom cable).

SpeedDOS works fine with the new cable.

With the cable detached, "Goonies" takes 1:45 min to load from disk. With the cable attached, loading time reduces to 26 sec. The numbers match what I see in VICE, so I am pretty sure the cable works.

Available in v4.3 which is now online.
