[Coco] Having fun with hacking HDB-DOS

[Bill Pierce]

Juan,
I'll give it a shot on my Coco 1 & 2 as well as in XRoar, but it'll be a couple of days. I have a big day at work tomorrow, but after that I should be free the rest of the week to test it out.
I'll let you know what I find

Thanks

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?

Juan
