    I can't seem to find that anywhere.
Did you try booting the BRU64K tape? Sounds like that should be a BRUSYS
system as well.

Not sure what the correct name is. I know it by BRUSYS, but there might
be some slight difference between the 11M and M+ standalone BRU, or it
might just be different versions of the same.

BRU64K also rings some bell, so I think I've seem that name as well.
    I booted it.   It seems BRU64K does not support MU: devices.   The
"regular" BRUSYS does.   I don't know what other differences there may be.
BRU64K "might" be able to fit into a system with merely 64 k RAM... (And might be older than your other BRU immage ...)
      Ok.   I was mainly concerned about the stuff fitting...I'm assuming
4.2/4.3 are larger than 4.1.   4.1 was the last version I ran.

      I've found the relevant sections of the documentation and am reading
it now.
Excellent.
    Progress!   I've restored the DL installation set under simh, moved the
RL02 disk images over to a (real) VAX, written them to RL02 packs, and
am running a sysgen on a (real) PDP-11/24.   It's midway through the
assembly of the executive.   I took a crappy phone pic:

    (yes, that bottom RL02 really is dirty...I'll clean it soon)

      I wish I still had that tape, but sadly it was lost many years ago.
Distribution tape for 4.1? I thought you had 4.3 anyway, so what would
you use 4.1 for?
    I wouldn't...but it was a pristine, original DEC RSX-11M distribution
tape, and those don't exactly grow on trees.

      Thank you Johnny.   I'm sure I will have other questions as I become
reacquainted with RSX.
No problems. Feel free to ask anything.
    Thank you!

    First question: I'd like to try to get DECnet running on this system,
if possible, to get it on HECnet.   I've never run DECnet under RSX
before.   I could put a DEUNA in the machine, but I am running short of
slots.   I have a DELUA, but I don't recall sysgen asking about DELUAs.
Are they compatible at the driver level?   Meaning, if I re-do my sysgen
to include a DEUNA driver, will that work with a DELUA?

                            -Dave
As I remember the SYSGEN/NETGEN task, the controller intended for DECnet should NOT be taken into SYSGEN at all, but later, at the totally separate task of performing NETGEN once Your OS. is up and running, it should be included there. So, no need to redo your SYSGEN when playing with different Ethernet cards.

BTW: DELUA replaced DEUNA...
