I've just acquired an old Sperry disk subsystem, consisting of a large
powered cabinet for 2 FH or 4 HH 5 1/4" drives, a Magnetic Peripherals
hard drive, and what is apparently a diffrerential SCSI to something
(ST-506?) controller. It looks and sounds to be in working condition, but
I need to know the basic configuration of the hard drive
Description - Magnetic Peripherals (CDC)
PN - 77731603 P# 177461
The defect flag sticker indicates it's got at least 4 heads, and at least
503 cylinders. The interface LOOKS to be ST-506 - at least it uses the
same cable set. The small user's manual that was packed with it suggest
that the drives are 30Mb, if in fact this is the original drive.
I'd greatly appreciate any information anyone could provide on this gear,
and for that matter on the Sperry controller board. Is there a reasonably
simple way to get from differential SCSI to single ended SCSI? If so I
would like to know the capabilities of the controller board as far as
supported drive capacities, etc.
Thanks in advance for any light shed on this mystery box ....
