I just won an 820-II on eBay, but the seller lost the external drive box 
(hard disk + 8" floppy).  Judging by the schematic, it should be very 
straightforward to interface one of my floppy drives to it (I have a bunch 
of Shugart, Seimens and Tandon units).

The hard drive I'm less sure about.  Looks like a proprietary interface of 
some sort.  Can anyone tell me more about it?

Does anyone have a spare 820-II drive enclosure they'd like to part with?

Lastly, will Imagedisk support creation of a system disk on an 8" drive 
attached to a Compaticard IV?
