It seemed like no one was responding, so I'm reposting with a better
subject...

It has a Shugart model 513 drive. How likely am I to be able to replace a
Shugart 801 drive with it? I know the 513 is DS and the 801 is SS, but
that shouldn't matter, right? It seems to want to conflict with the
other 513 drive in my ACS-8000, and also doesn't want to light up its
'selected' LED at boot when I jumper it to DS0. Is there some sort
of jumpering on the drive I need to change to get it to work with the
ACS-8000, do I need to rewire the cable, or it it easier than it
seems? Does anyone have a pinout for the connector?

Also, would it instead be possible to use a CDC Model Number
(Equipment ID) BR8A2A, Part nymber 7574025 drive? I have the CDC drives
and pinouts, but using them guarantees the drive won't fit properly into
the case, and I'll have to at least solder on a card edge connector and
adapt the power input connectors for the drive to match the computer's
connectors.

All in all, a fair amount of work either way I end up doing it...
