[Coco] Seeking ECB Rom in the US

[Bill Pierce]

Kip & Sean,
I'm not sure, (I know I'll be corrected if I'm wrong), but you cannot put the HDBDOS rom in the Coco ROM space with the CB & ECB. It goes in the Disk controller or a rompak. The HDBDOS rom is hard coded for the Disk rom area (it is a replacement disk rom) and would not work if mapped to the CB/ECB area. Unless there's a way to map it higher to $C000 this idea will not function. CB & ECB map to $$8000 & $A000. You may know more about the mapping than I do as I'm just going on what I've gathered from others. I'm no techie.

Kip,

If I can get Drivewire on boot that would be nice. I was going to
 just hook up an 
.MP3 player with the loader on it. I'm not too hung up on getting
 CoCo 3 stuff going
Mostly I just want to get my games catalog going, and maybe some
 light programming.
I have fond memories of beating the crap out of ECB when I was a kid.
