Hi
I've acquired two PDP-11/44 and have just now gone throught the list of
cards in the cpu-boxes and the spares. Here is a list:
http://www.update.uu.se/~pontus/slask/11-44-kort.txt
Nothing special, I've used the field guide to identify most cards. I've
only marked one card of each kind.
There is two cards connected with ribbon cables that I can't identify.
They are made by Data Management Labs in San Jose and are labled DML 750
Board A and Board B. There are some numbers as well (in no particular
order)
980-8043
710-1921-001
There are some bitslice chips and a whole bunch of roms. Anything that
rings a bell with anyone?
Also I wonder what the
"M7251 KG11-A U Network interface XOR and CRC block check option"
"M3110 DRCSA U Protocol assist #1 w/special character check and CRC
(DEC/DLC/DRCSA)"
"M3111 DRCSA U Protocol assist #2 w/special character check and CRC
(DEC/DLC/DRCSA)"
are used for?
Cheers,
Pontus

Hi Pontus,
congrats on this acquisition.
I've acquired two PDP-11/44 and have just now gone
throught the list of
cards in the cpu-boxes and the spares. Here is a list:
http://www.update.uu.se/~pontus/slask/11-44-kort.txt
I had a quick look at the list.
When looking at Expansionsl?da 2 (l?s) I frowned seeing the 11/24
CPU module there. Now, I don't now if you wrote them down in the
order the modules are in the slots (like the first 11/44 CPU), but I
think you better check all positions before applying power!
Now, my Swedish is nill, but I think "l?s" means something like
"loose" , "just a bunch of modules" put together in the expansion
box, where the expansion box functions as a storage drawer.
I use BA11-K boxes too as storage boxes ... never apply power!
There is two cards connected with ribbon cables that I
can't identify.
Sorry, can't be of much help here.
Also I wonder what the
"M7251 KG11-A U Network interface XOR and CRC block check option"
"M3110 DRCSA U Protocol assist #1 w/special character check and
CRC (DEC/DLC/DRCSA)"
"M3111 DRCSA U Protocol assist #2 w/special character check and
CRC (DEC/DLC/DRCSA)"
are used for?
AFAIK, the KG11-A "belongs" to serial comm cards and adds
error checking on the data stream. My guess is that the M3110/3111 are
modules that "seek" for a special character and generate a CRC for
error checking purposes ... just a guess.

You are right, l?s is loose, the box doesn't even have a power supply. I
was to surprised to find a 11/24 there. The box has a card listing from
an 11/24 on it, but the rest of the cards probably come from the 11/44.
There is two
cards connected with ribbon cables that I can't identify.
