Well ... the most common SE card for Suns (and the one which I
use for SE SCSI) is marked 375-0005 by Sun, and is the Symbios SYM22801.
There is a version marked 375-0013 which has a FCode ROM on it for use
with systems which don't already know about it -- but I've never needed
them with my Ultra-60 systems. the 375-0005 can usually be found by a
search on eBay -- and most of the time you can find quite reasonable
final prices.
It is a dual SCSI card, with VHDCI 68-pin connectors for both
controllers on the card bracket to feed to the outside, and both
50-pin IDC and HD68-pin internal for each controller. There are quad
DIP switches for each, with switch element 1 enabling the 50-pin SCSI,
switch element 2 enabling the internal 68-pin connector, switch element
three labeled "upper address bits" (I guess making the 50-pin connector
think that it is talking to SCSI-IDs 8-15 instead of 0-7. And switch
element 4 enables the external 68-pin VHDCI.
So -- you could enable one for the internal 68-pin for your
internal drives and still have the other to connect to to external drives
if you wish to add them later.
Note that it should go in a 33 MHz PCI slot, not a 66 MHz one if
your computer has one. (Not likely in the Ultra-10. :-)
Good Luck,
DoN.
