There is a person that has requested that the disk drive and disks be 
dumped if that person should win.
 
There are 2 disks marked "system" on them.

   As a part of The Unix Heritage Society, I believe we need to keep 
this system intact. I personally do not have the money to successfully 
bid and win. I hope somebody from The Unix Heritage Society will take up 
the cause and make a successful winning bid. The system in it's entirety 
is a part of The Unix Heritage.

Why do you think the disks are Unix-related?

I'm not saying that it's impossible to run Unix on a 11/23 (in fact I
was the one who recovered RL02 packs with V6 hacked to run on a 11/23)
but it's 99.99% certain that this system ran either RT-11 or RSX-11,
given the context.

Now, if the buyer is dumb enough to buy the system and not use the
disk drives, it's his responsibility to figure out how the heck he's
ever going to boot the OS.

Tim,
    I thought Unix was written and used on PDP-11 systems.
    Which PDP-11 systems ought I keep an eye out for?

Thank you,
James Falknor

It was.  So was DOS-11, RT-11, RSTS/E, RSX-11-*, IAS, etc.

Anything but the very lowest end (11/04, 11/03, etc.) if you want
to run Unix.

While Unixes show up on -11's in many applications, they were
least popular in industrial-control type situations, which is where
most -11's are used.  Of course, just to complicate things, they
were using Unix variants on 11-based industrial control systems too!
And you are right, it is indeed possible that this particular 11/23
has some Unix packs in the deal, I'm just pointing out that it's
unlikely.

And you were especially correct that a buyer would be unwise to
ditch the drives and packs.  An -11 is more than just the CPU box,
if you want to do anything even vaguely useful/interesting!

Tim.
