Hey, that's me.

I don't know.  I have never used Atari Disk drives.  I do know that
you can only hook up "low" density 3.5" drives to the Rainbow.
The high density disks won't work.  From conversations that I have had
with other people, this is due to a data transfer rate that is too
fast for the Rainbow to handle.

The other problem that some drives have is that they don't have a
"Ready" line.  The Rainbow's disk controller *REQUIRES* that the ready
line works.  The ready line is usually listed in the spec sheets for
mail order drives as not used.  In these cases, you have little choice
but to wire that pin (I want to say pin 40) "high".

If you would give me a call at work (303) 678-4748 in the afternoons
(Mountain Standard time), I may be able to lend you a hand.
