Life got in the way, as usual, but here are a few CDROMs to start with:
Hopefully those will be accessible to whoever wants them.
AG-MN36G-RE and AG-PASMA-RE are discs 1 and 2 of NOV-1989 CONDIST.
AG-NC67C-RE is the JUL-1987 CONOLD.
AG-NH36B-RE is Disc 1 of 2 of the JUL-1989 "VMS AD Software
Consolidation", which I think was some sort of experiment.

I've no idea whether the nearby GAME store has a polisher, as they've
not replied to my queries and I've given up waiting. I'm going to try
2000/3000 grit sandpaper on the MAR-1989 CONOLD soon, so we'll see how
that goes (I picked up some rubbing compound today, which is needed for
the final stage).
I do have a few more early ones imaged, I just haven't scanned the CDROM
themselves, so as soon as I get that done (hopefully less than a month
this time!) I'll upload those and make a note here.
These are tar images compressed with xz. "-J" should expand them. There
is a sha256sum.txt file inside and a readme with details of the
extraction and the results of the ddrescue command. I think AG-PASMA-RE
read without error using dd.
