[Coco] Having fun with hacking HDB-DOS

[Juan Castro]

Finally got back to this hack. I now have a ROM with
software-selectable DriveWire routines. To reiterate, this is for CoCo
1 and 2 only.

EXEC &HE002 selects 38400bps (CoCo 1)
EXEC &HE005 selects 57600bps (CoCo 2) -- this is the default at boot
EXEC &HE008 selects the Becker port

Next steps: including more options (IDE!!!) and devising a friendly
syntax for the selection. Then, find a way to select the disk routine
per drive. Ideally, you should be able to plug a SuperIDE, a floppy
controller, and a PC by RS232, and copy things willy-nilly amongst all
three.

The ROM:

The patch against the Toolshed repo:

Anyone wanna test?
