[Coco] SuperIDE backup/restore

[Mark Marlette]

Mark,

SuperIDE = IDE = CF parrallel data xfer, which I know you know... :)

CPLD, IIRC, as I didn't writ the drivers, busy is detected by bit7 while polling a status register.

I do have Ed's CF and SuperIDE.

Ed- How did you determine that the CFs were a bad image on the CoCo?

What was your procedure, exactly. Need to reproduce that here in the lab.

Regards,

Mark

I doubt it's the driver. It's more likely to be the SD interface.

Could be a timing issue on the SD controller; wondering if it's
implemented in a CPLD? And is it SPI mode? Is there a 'busy' status that
is not being handled?
