How did it die? Sometimes it's just a cry for attention :-)
I've salvaged mine twice so far!

Quite right too!

I've just checked and the M38 manual does describe it quite
clearly with a picture.

I don't have one but, looking in the manual, the only suitable
one I see if for the TZ30. I have a similar one in a VS4K90
and a quick measurement suggests that it would be just right
for an RRD42 (and hence, probably any other DEC CDROM).

While waiting for a complete cover that fits, you could make up
a temporary one (from wood or even cardboard) just to keep the
dust out. It won't be pretty, but it will avoid any irreversible
modifications to the existing bezel.

All my CDROMs are external. It makes it easier to move
them around for installs etc.

Maybe it helps for RAID or striping?

The VS3100 SCSI controllers are really old. Wide did not
exist in those days and SCSI-2 probably didn't either.

VS4K9x has TC and I think VS4K60 has too - I'm pretty
sure that the VLC doesn't. A TC NI does exist so all
you need is a driver (I don't know if one exists or
not). I think that you need a plug in board to actually
have a TURBOchannel - the manual is on the web now so
that should be easy to check.
