There's never a QUOTA.SYS on a CDROM, so that's probably OK. Not sure
about the SHORTBITMAP (it's been a long time since I used VMS as my
daily driver and I've not had the chance to try an ISO that was read
with no errors, nor a real CDROM in a real CDROM drive on a real VAX).
I've just tried ANALYZE/DISK on VAXBINMAY931 which is the oldest I can
put a hand on right now and it gives exactly the same output as you got.
I plan to include the ISO, a README.TXT that explains that these are all
incomplete and I'll attach the ddrescue output, a scan of the CD, a
SHA256 of the files. I'll tar it up and compress with xz.
If anyone would prefer some other format or compression or whatever, I'm
open to suggestions.
ZIP is probably most commonly used for compressed archives on VMS. The
version of ZIP that runs on VMS can save VMS file attributes when told to so
that it doesn't lose important attributes for the installation kits like tar
would. (I only came across xz anywhere for the first time about a week ago...)
