re-seating the cable had no effect, but a little experimenting got me a
command that would boot the cd:

boot /sbus/esp@example.com,800000/sd1,0:c

It started a boot, but failed like this:

SunOS Release 5.6 Version Generic_105181-05 [UNIX (R) System V Release
4.0]
Copyright (c) 1983-1997 Sun Microsystems, Inc.
Configuring devices. . .

type=0 tsid=0
syncing file systems... 19 19 19 19 19 19 19 19 19

19 was printed about 50 or 60 times.

Than it followed with:

cannot sync -- giving up
rebooting...

What came next was a power-on reset.

I suppose that this is progress of a sort, but perhaps it's the case
that either this CD-ROM is

a) Bad (I've never used it before)
b) Not very compatible with Sun hardware
c) Just not fast enough for the task at hand (it's a 2X caddy type)

Or all of the above.

I tried Jim's suggestion of reversing the DIP switches, but that had no
effect either, which makes me suspect there may be a problem with the
drive.  I'll try hooking it to an Intel box and see what happens.

Is the controller manual (or any other SS2 documentation) available
online anywhere that you know of?  I have none at all.

Anybody got one they'd like to come and visit me with?  :-)

The internal disks are both SCSI-2, and I know for sure that the smaller
one works, since it came with the machine and has an old SunOS on it.
Or does that problem with SCSI-2 only apply to external devices?
