2133 3x3 case
2155 5x5 case (bigger)
2168 tower unit
2011 and 2121 used special monitor with computer's power supply in it.
2123 used either a ps2 model 30 or mod 55sx low profile case.
interesting fact: some midrange 486 ps/1 models were netware certified!

There are 2 basic versions of the 11/53 CPU. They both have 2 serial ports.
1 has 1/2 meg on board the other has 1.5 meg on board. They are both
available with Sbox handles for use in BA213's. If you are looking for one
keep your eyes open for DECserver 500 and 550's. The 500's use the 1/2 meg
version and the 550's use the 1.5 meg. There is some difference in the
firmware used on the DECserver CPU's from the usual PDP11/53 but I have
never taken the time to play with them. I just put in the PDP11 firmware
and run them.

Nope...the 11/53 is a J11-based quad board with some memory and SLUs. I have
a couple of them here in BA23s, waiting to turn them into BSD2.x boxes. I like
'em.

I found this article in the September 22 issue of the Montreal
Gazette:
ST. LAURENT SUED FOR COMPUTER-FIRM RAID
George Kalogerakis
Gazette Justice Reporter
------------------------
A computer recycling firm is suing the city of St. Laurent for
$36 million, saying the municipality destroyed millions of dollars
in computer parts when it sent backhoes into the company's
warehouse.
Backhoes broke through the garage doors of A1 Vente Ordinateurs'
building on Stinton St. on Thursday morning, the lawsuit says.
The machines then used their shovels to scoop up computers stored
inside and drop them into waiting dump trucks.
This went on until A1 got a court injunction to stop the raid
that afternoon. The city's crew returned Friday morning, and A1
obtained a second injunction Friday afternoon, halting all
operations.
St. Laurent city officials were not available for comment last
night.
The equipment was sent in as part of a zoning dispute between
A1 and the city.
St. Laurent has criticized the company for stockpiling discarded
high-tech parts outside in an unsightly manner. It also claimed
A1 was illegally using the site as a truck depot.
So they went to court. In August, Superior Court Justice Vital
Cliche ordered A1 to suspend operations and clean up the outside
site.
The company was given 30 days. If it didn't do the work, the
city would and make A1 pay the costs.
A1 general manager Mike Brown said yesterday the cleanup was
done. It cost $8000 for trucks to haul away all the discarded
parts, enough to cover a football field.
Brown said A1 buys computer salvage by the truckload from
bankruptcies and governments. What can be reused is stored in
the warehouse while the junk is left outside.
Court papers filed by A1 say the firm had complied with the
cleanup order.
But the city arrived Thursday at 7 a.m. and broke into the
warehouse, which was not part of the judge's cleanup order, Brown
argued.
The 14,000 square-foor building is usually filled with 8-foot-
high stacks of good computer parts, to be sold to brokers or
repair shops that need parts.
"They just destroyed it all and then took it all away," Brown
said.
He added about three-quarters of the computer stock had been
hauled away as garbage by the time A1 got its injunction on
Friday. What remained was about $10 million in stock.
Brown said that's why A1 is suing St. Laurent for $36 million -
$30 million for the computers that were hauled away and $6 million
in damages.
He said videotape and photographs taken by staff can prove
the city acted maliciously.
For example, he said, the warehouse is split in two. In the
front is a display area with offices on the second floor while
the back is the storage space.
Workers sent by the city were pushing computer equipment off
the second storey, where it fell 15 feet onto the concrete floor.
He also claimed people were taking computer screens and putting
them in their personal cars.

Huh? Is the CPU chip on an 11/53 card an F-11? If so, is it the same
speed as an 11/23? I have 11/23 dual-height CPUs, 11/23+ quad-height
CPUs, but no 11/53 (nor 11/73) CPUs. I did see one about 11 years ago
as I was trying not to see it on my way out the door to start my two week
camping vacation. It was quad-height with some quantity of RAM on it
(1Mb? 1.5Mb?) The worst part about that experience is that the boss was
trying to leave, too; and it was a disk replacement job on a MUMPS box. :-P

IIRC, there is no MSCP support in 2.9. I have it (from waaay back, not
via PUPS) and ISTR having to load it onto RL drives, RK drives or RP
drives (or third-party XP (SMD) drives). I forget about 2.10BSD. I'm
certain that 2.11BSD supports MSCP, but might not be so happy on an 11/23
unless you've got at least 1 Meg.

for those of you interested in 3270, there's a card on eBay right now,
exactly like the one I recently offered for $3.20 (the postage for priority

Groan...to have complete system needs one rack... that pretty large
by my space standards. But my eyes lits up on that 70 lights...
whew!
Which series is most compact (sized for desktop or tower style) pdp
or vax and only needs one wall power cord to run whole thing
(including storage built in).
Current draws snipped. Even I did manage to bull through my parents
and did gotten that 11/70, breakers will trip every time I power just
the cpu itself up. I throw out flames at my parents every time they
accidently tripped the breaker with that ac unit making my computer
go out, all plugs in my bedroom and few in living room including my
alarm clock and shop computer go dead. I hated this apt even it's
located in nice location, nice people. But I do have 2 negatives
about this apt, floor is very bouncy for a uneven cement floor (too
thin?) and too few breakers on too many circuits attached. Landlord
turned down the request to put insolated circuit and a breaker just
for ac even we did pay the electrican ourselves. Lots of space in
that breaker box, 5 spaces left actually.

I have just taken out of service two 11/70s, one operational and one not. Both are complete. I also
have two RMO 5 drive packs with 300 meg drives.
Any offers?
