I have collected a pretty good amount of info on both of these drives,
mail me for details.  Im intrested in sharing info with you.

On the subject of the 9090 drive, has anyone successfully been able to
format past the 7.5 meg limit yet?  I can format just about any hard drive
with that tandon/omti controller configuration, but only out to 5 or 7.5
megs no matter how big the winchester.  Anyone know what address in rom,
and what rom chip the drive table is in?   Any killer programmers out
there that may have written a dos patch that sits in one of the data
buffers of drive ram that allows for more then 7 megs?   Im a pretty good
programmer of 6502, and am expirenced in working with ML programming 
commdore disk units.  All I need is a rom guide!  Anyone who can help?

Come on!  Lets put CMD outa business!! <GRIN>
 
PS - Anyone who has ever seen a CMD hard disk in action will notice the
LED's on it act EXACTLLY the same as the 9090 drive.  I think someone
must have figured this out, just is not talking!
