[Coco] SuperIDE and floppy disk

[Mark Marlette]

That is an old one...thought I tried it though. Third party controller's might not follow the proper decode, but Tandy would have.....

I would suspect it very highly due to it's history.

fd-500 and the coco hangs for a while like halt is low.

this same fdc that was connected to my coco2 (the one which blew) the halt line remember? maybe the fdc is faulty?
