[Coco] Disk Problems

[K. Pruitt]

That fixed it.  I feel like a complete idiot.  The controller has gold
contacts so I didn't even bother cleaning the connectors believing that they
were immune to oxidation.  30 seconds with a pencil eraser and all is
working again.  I saved a quick basic program to disk and then ran diskini
on the disk and all is good.  Thanks, Arthur.

Odd that it worked under OS9 but not RSDOS.

Have you tried cleaning the disk controller's contacts with a pencil
eraser or some such thing?  You'd be surprised how often oxidation is
the culprit in weird disk-related failures.

And no, OS-9 makes no use of the ROMs once it is booted up.
