I'm glad you mentioned CD-ROMs on Q-Bus SCSI

occur to me previously to try that. I just gave it a try and got it
to work.
I have a Dilog SQ706A Q-Bus MSCP SCSI controller. I cabled it to a
Plextor PX-6XCS SCSI CD-ROM. I used E11 to boot the RL02 XXDP disk
image and created a bootable RD51 XXDP disk image. Then I used CDBURN
on Windows 2000 to burn the RD51 disk image to a CD-R as though the
disk image were an .ISO image. Then stuck the CD-R into the PX-6XCS
and booted it up as DU0 on the SQ706A in the 11/73 into XXDP. I
flipped the 512-byte block switch on the PX-6XCS before trying this
thinking that was probably necessary. I just flipped it back and
tried again and verified that it doesn't work without the 512-byte
block switch being set.
Cool! is this the Caddy 6x drive? I collect the Plextor caddy drives
whenever I can find them. I think I'm up to 3 6x drives, and 1 8x
(which is the drive in my PDP-11). Now you also know how to get more
interesting OS's on your PDP-11 :^) Though I've yet to figure out
how to get RSTS/E to come up from a write protected CD, my memory is
feeling fuzzy this morning, but I don't think anyone else has either.
For the limited number of CD's you'll find for a PDP-11 caddy drives
work great. Basically there are the two DECUS CD's from Tim Shoppa,
and what you make yourself.
So now I assume that if my MicroVAX-II/III box is
working OK and if I
obtain a VAX VMS installation CD I should be able to use the SQ706A in
the MicroVAX box to boot and install from the VMS CD. I'll have to
give that a try.
That is correct. Do you have the Hobbyist Licenses yet? You'll
probably want to start working on that first.
