The most recent that I have from you for OST is 19, Ultrix-11. I don't
have anything past 9, OS-8 (!!). So I'll be delighted to shovel those
into my sources, THANKS!!
I /did/ have a few questions (naturally)
First, what do you do after you get the foreign configuration message in
NFT? Send an access complete and close or just close? I punt the
connection, and was wondering whether that might be considered a rude
thing to do.
Second, what does DTS/MVS mean?
Finally, Ultrix-32 as a file system reminds me of something that I had
been thinking about, which is that a number of operating systems can
actually concurrently run multiple file systems.
As an arcane example, one time I was walking past 2102 (Tops-20 Monitor
Development) and almost fell out of my sneakers seeing that it had a
Tops-10 disk pack mounted. After checking that it wasn't a dual port
set exclusive to one of the nearby (beautiful) KI's, I saw that Tops-20
was really using it. Wow. It's true, the hooks to use Tops-10 file
systems remain in PA1050. Tops-20 also treats DECtape as a different
file system, but I can't imagine what it would be reported as.
Clearly Unix can run a bunch of different file systems, so I won't get
into listing those.
Windows/NT, 2000, XP and I forget what else can run FAT12, FAT16, FAT32,
HPFS and NTFS.
I had been wondering how DAP might accommodate this, or whether it
needed to.

That matches what I see from RSX. Tops-10 looks almost broken, if you
as me. I suspect it just wasn't developed and tested much in the
latter days, compared to TOPS-20.
I have a slightly more up to date list in RSX, but I extended it
further based on observations myself.
I think I posted it before, but anyway:
