I just ran across a sale on epay by a guy who thought
you could pull
the processor chip off the board and sell each in separate auctions.
There are a lot of idiotz out there.
I ran into one who'd removed a group of boards from (probably) an -11/40, and
then scrapped away the rest of the machine (including an RK11-D backplane).
I took _great_ pleasure in informing him that the stuff he'd scrapped had
been worth several times what the boards he had 'saved' had been worth.

Many years ago, before I discovered that people actually valued and collected this useless
junk I bought a Northstar-in-a-desk at auction, threw the innards in the trash and kept
the desk (now holding a stack of Cromemcos ;-).

The fellow responded and as I had suspected had never seen anything this
old before and had thought that the parts were separable. He will be
possibly re-combining them later. (I had figured he did not know it was
not a case like PC's where the processors and MB's were routinely
separated).
I'm sending along the link and contact to some who PM'ed me as well.
Also he is going to hopefully share photos of the entire pile and I'll
try to help him market the parts in the most profitable way for him. I
and the PM'er who will know who he is will hopefully rescue some stuff
that way.
Thanks

sure how far down it is all been taken though.
When pulling apart old stuff 90's test equipment, advertising scrap, and
the like they make more than trying to treat everything like a museum
artifact. The thing is do they keep doing it once you tell them. I
think this guy will listen. we'll see.

Are there any reasonably priced boards with the processor and memory of
either the KDF or KDJ processors?
The ones I've seen recently are astronomically priced. Would be
interesting to find one with memory, processor and console.
Thanks

I don't remember the board numbers that came with the memory. If you have
specific boards I'll try to check tonight.
I seem to remember some lose J-11 chips somewhere- I'll try to find them.
Thanks, Paul

IF you want to take a different path find a Pro350(KDF-11) or Pro380(KDJ-11)

A complete system is usually cheaper than the random boards. I know I
have two sitting.

I picked up a couple of the DECserver 550 version (1.5MB RAM instead
of 512KB) for closer to $50 each, but that was several years ago.
The 11/53 version without the S-handle bracket seem to be a bit less
common. I managed to also grab one of those on eBay a while ago, maybe
less than $100 at the time.

Indeed. I'll have to check mine to see if I have an M7554-SC (512KB)
or M7554-SE (1.5MB) There appear to be a large number of types of
M7554 in the field guide - different handles, different board etches,
different boot ROMs...

Those were usually found in late-model MicroPDP-11s, and not as
plentiful as some types of PDP-11, IME.
I worked with one in Aug, 1988 that was running MUMPS (a customer
wanted our company to bump up their storage - that was an adventure as
neither of us doing the work had ever used MUMPS before, and it was
all menu-driven and nothing like any other PDP-11 OS that we had
encountered before).
