I asked:
Sorry to ask this here, but at least it's DEC related. I'm looking for
device drivers or something that will let me use the RRD42 with the
Adaptec SCSI card in a pc. Do they exist and if so, where? Thanks.
I hope the following don't mind if I use their wise comments to help others
who may have had similar problems.

You could use the drivers from Adaptec that came with the EZ-SCSI
software from Adaptec also.

This should be no problem. The docs don't mention the RRD42 as a compatible
CD-ROM, but they do say that any SCSI-II compliant CD-ROM should be. This one
is! If the following doesn't work, you probably need upgraded software from
Adaptec (I only got my card 3 weeks ago).
Plug the RRD42 into the SCSI card (preferably with a SCSI ID > 1, some Adaptec
cards seem to expect anything on ID 0 or 1 to be a hard disk). Then you need
the ASPI dos driver for your card, the ASPI CD driver and MSCDEX, as follows:

DEVICE=C:\SCSI\ASPI4DOS.SYS /D # I have a 1540CF card
DEVICE=C:\SCSI\ASPICD.SYS /D:ASPICD0
Autoexec.bat
C:\SCSI\MSCDEX.EXE /D:ASPICD0 /M:12 /L:E # and whatever other options
The EZ-SCSI software did all this for me as I had the CD-ROM connected when I
installed it.

If you remove the "parity" jumper, RRD42 CD-ROMs respond as
the Sony CD-ROMs that they really are, instead of using
the DEC specific firmware and device name.
Sorry, I can't help with actually locating a device driver,
but I'd expect any of the standard SCSI suppliers to include
one for Sony CDs.

The RRD42 in my experience has been a Sony CDU-541. There is a jumper
block on the back of the drive itself, inside the enclosure if it's a
standalone unit, next to the audio output that is used for the SCSI ID
and the "mode". Mode is the leftmost set of pins followed by ID0, ID1,
and ID2 from left to right.
There are two modes, 0 and 1 with 0 being without a jumper, and 1 with.
These are how they are defined in the RRD42 Disc Drive Owner's Manual.
Mode 0 -- Default mode. When the drive is shipped from
Digital, the jumper is NOT installed. The drive operates in
the default mode with a block size of 2 kilobytes. Use Mode
0 under MS-DOS and SCO UNIX operating systems.
Mode 1 -- Standdard mode. When the jumper is installed,
the drive operates in standard mode with a blok size of 512
bytes. Use Mode 1 under VMS and ULTRIX operating
systems.
I've found that making sure that the Mode jumper is open and using
Adaptec's aspi drivers works fine.
And I got one nasty reply from a fellow stating I should stay off this list.
I'm glad the helpful/arrogant ratio is high. :) I do apologize though for
asking this question but I thought it would be appropriate to ask a question
regarding a Digital drive product.
