Save for all the DEC stuff I've encountered. Casters and adjustable pads.

IBM never released the schematics, even to internal IBM sites wanting them.
Early on, we learned that there was a optoisolator that often died.
There WERE aftermarket schematics available for about $40 in the mid-80's;
I don't
think I have any?? A friend still at IBM may.. I'll ask when I see him.
The XT versions were a lot more reliable; I have 8 XT's that get turned on
only once or twice a year, now, and I've never lost a power supply or
system board.

Thank you! Please forget about the VMS part. I have got an solution.

In September of 1981 while in England I happened upon a computer show. I
said I was with the Northwest Computer News and got a press pass. Our local
computer club newsletter was a 12 page tabloid size newspaper. I interviewed
many vendors and took notes. After a trip to England I talked with the
editor and she wrote this story for the October 1981 issue.

The Brits on this list can tell me if I got the story right.
There will be an Homebrew Computer Club 30th Anniversary Retrospective at
VCF 8.0. Here is my web page on my time at the Homebrew Computer Club.

Dear Alan,
As this topic is quite old, I 'm not sure you will really see my answer.
Anyway, if you're still interested in this machine, I can give you help, as
I'm the owner of a complete IBM 5280 system (ie IBM 5288 + two IBM 5285 +
printer IBM 5222)with full disk systems and maintenance documentation.
Let me first inform you that neither 5285 (nor 5281) are albe to work alone.
When you start them up, they try to deal with the master controller unit
(MCU) IBM 5288, on which is implemented the system.
If it can't dialog with the 5288, you'll get only three lines of characters
on the screen, which are a kind of autotest. As far as the floppy drives are
concerned, it's quite the same. Indeed, these floppy are not part of the
5285 machine, but are extensions of the MCU 5288 on your local working
station. So, when you insert a disk inside, it's absolutely normal that you
don't have any answer on your display, as once again the 5285 is trying to
send the data read on the floppy diskette to the 5288 system.
Owning a 5285 / 5281 alone has no really interest, as it's neither a dumb
terminal and won't be useful. But it's a beautiful old machine.
All this system called 5280 is dated from 1981. Mine has been working
beetween 1982 - 1987 night and day. Now I only make it work when a friend of
mine want's to see it working, as it's really worth seeing. Unfortunately,
I've broken a keyboard and noy I've only one working station instead of two,
and my printer has no more ink ribbon :-(
Best regards. Fred (from southern France )
Hey, what's this thing? Some alpha board?
It has Digital logo all over, pen scribbles on the outside of the box
saying "Single DSSI controller for 4000's" and the barcodes read
"54-22444-01" "B01" and "KA344DFR04"
Inside is static bag containing 4 inch by 3.75 inch pc board. The big chip
(surface mount) with a zillion pins has a 1"x1" two-fin heat sink. There's
another two small chips and what looks like mebbe a 16.000000 mhz
clock/osc. Three address jumpers marked "4" "2" "1"
Connector on top looks like 96 to 100 pins, shaped like a scsi SCA but longer.
Connector on card edge is 50 pin blue with locking ears.
Silk screen reads "DSSI Daughter card" Back 'o screws and bracket in the
box too.
Anybody want it? Any reasonable offer accepted, meaning offer me more than
I paid for it (not much) plus shipping and it's yours.

Really a 32 not 33?? 32 is 5-bit Baudot, as I recall.
