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.

That is correct. Do you have the Hobbyist Licenses yet? You'll
probably want to start working on that first.
