[Coco] Disto SASI-SCSI to MFM, Corrected

[Bruce W. Calkins]

One used a 34 wire ribbon cable, split in the center, with the outside edges
moved to the outside of the 50 pin connector.  (Or was one side moved to one
pin short of the outside?)

According to the documentation I have, the Disto hard drive interface could
drive two Adaptec 4001A cards with two MFM drives each.  What was not in the
Disto documentation was the fact that the second Adaptec card needed a trace
cut to allow it to function as the second unit.  That bit of information is
in the Adaptec technical manual which I was fortunate enough to score one on
eBay.  Other SASI or SCSI-to-MFM cards may or may not have similar details.
