I have a fair bit of experience with these.
is a Cipher 880
I would get pictures of the unit. 9610's don't look like this, they have
a card cage in the back and a completely different control panel. Docs/pics
are on bitsavers for the 961x which is your best reference. From memory, 9610
vs 12 was 800bpi support (I need to check the manual to be sure).
Now, as far as the 961x goes, there were lots of different versions. The basic
drive is Pertec interface, with an optional SCSI board. The SCSI can have
varying amounts of buffering.
They have strong servo motors, and they run fast. Not good for sticky tapes.
Their 800bpi recovery is pretty good, and the available documentation is
excellent. I wish the M4 Data or HP 88780 docs were half as good (you know,
like including SCHEMATICS in the service manual).
The 961x has a rubber wheel, and the go gooey, but so do the M4 and 88780
Of the three drives, the M4 has the softest servo, the HP, then the Kennedy.
Softer servos can let the tape go slack and swing the tensioner farther, esp
if the tape hasn't been condtioned (packed on a tape cleaner).
