The controler card has a MFM controler, with room for two data cables and
two control onces and a single scsi connector, the scsi connector was only
used for a archive corp interface board that does scsi to qic-02 interface
from what I have been able to dig up.

If just I can get one of my mfm cards be it the 2090 in my amiga 3000 or
the noname lcs one to work with the drives so I can get dd image of them,
I can always worry about how to make sense of the data later.
Is a good excuise work with my amigas again, havent used them in a while
even though they are sitting on my deck right in front of me.
