[Coco] CoCoSDC and SuperIDE together was SDC Troubles

[Allen Huffman]

For OS-9 disks, both SuperIDE and SDC drovers can run at the same time with no problem.

For RGB-DOS/HDB-DOS you run out of that then use a BASIC program which can send commands to SDC to mount and create disks. Then normal
backup.

I had a BASIC program that copied all 256 HDB-DOS images over to DISK000.DSK to DISK255.DSK.
