I used these settings in my format.dat file for a Sparcstation:
ncyl = 772 ; acyl = 2 ; pcyl = 774 ; nhead = 8 ; nsect = 33 ; rpm =3600
The SCSI ID is set by three jumpers next to one of the large custom chips
on the control board. The jumper nearest the edge of the board is ID0, the
one nearest the chip is ID2. Jumper fitted = 1, unfitted = 0. I don't
have any jumpers on other pins.
There are some pins on the front, in a 14-pin connector. I can't remember
what they all do except that the pair nearest the centre of the drive are
for the LED.
This drive doesn't spin up until given a Start Motor command, and the DEC
firmware is different to the standard Connor firmware so there is no jumper
setting to control this.

It is.
And Conner was recently bought by Seagate, which has a
pretty informative
web site. Try looking it up there.
The diagrams there, for the "obvious" Connor equivalent, are mostly correct
for the RZ23, IIRC. That's where I originally got most of the information,
a couple of years ago.
