[Coco] Becker interface for Coco 2 emulators

[Ron Klein]

Hello everyone,

Does anyone know what the correct HDBDOS ROM would be for using Drivewire
(via the Becker interface) with Coco 2 emulation?  I would need this for
MAME.

I found reference to one ROM file: hdbdosdw3cc2.rom

I get the following string upon bootup:

HDB-DOS 1.1D  DW2  COCO 2

While the Coco 2 driver starts up in MAME, it doesn't appear it actually
communicates with a Drivewire instance.

Thanks!
