The LA180 cable (at least for use with an LPV11) is a BC11S-25.
That is a round cable with a 40-pin BERG on each end.
I couldn't tell you if all the pins are used or not,
or if the connections are pin-for-pin.
The LA180 engineering print set is available at?? http://vt100.net/manx
although it is in two parts, in multi-page TIFF format, takes up 20 MB,
and takes FOREVER to load in Windows.?? Would be nice if someone
converted it to PDF format.?? ;-)

Another attempt to see if my replies to the
list come over a bit better.
I have set and checked all suggestions, and change the font type to
Courier New after typing the message. If this message gets to the list,
I will see how it's presented. If it is still bad, I better stop using
webmail, and switch to Outlook Express (and keep fingers crossed) ...
The LA180 cable indeed is the BC11S-xx where xx stands for the length in
feet (25, 50 or 100).
I checked visually, not all 40 pins are used. At both sides 19 pins are
wired, first 2 pins, then one open and then 17 pins. The print set will
show which pins actually carry signals. Ethan already mentioned that he
used a straight 1:1 flatcable.
:-) I scanned the 2 parts multi-page TIFF back in the days when the Oc?
3165 scanner and image processing only output was TIFF. It still is, but
nowadays you can select "pdf". It is still TIFF, but with a "pdf
jacket"
to present the data easier (acrobat reader). I don't work for Oc? anymore
but I still think the 3165 (or successors) is a very nice copier/printer
and scanner (600 dpi, 8 bit, 256 grey scale).
Windows 98 has a very good TIFF viewer (in "accessories -> imager") from
Kodak, IIRC.
thanks,
Henk.

Make sense.

It may have had the standard DEC "flipped connector" on one end, but I
think that's just a mechanical convenience to fit easily into each
end, not an electrical difference.
As for someone on the list (don't have the posting in front of me)
mentioning serial versions of the LA-180, with an additional board
inside, yes, I do remember they existed, but 20 years ago, I don't
recall them being common - we always had lots of ports on our DEC
machines, either DZ-11s or Emulex CS-21s or DEC DMF32s - at least
8 ports per machine, unless it was for development, engineering, or
office work - then it was 24-32 ports per machine (so that folks
could have more than one port going to their desk - we never went
the route of terminal servers for a variety of reasons). It would
have been very handy to have a medium-speed wide-carriage printer
on more than one machine at a time - something we _did_ do with LA100s,
albeit at a slower speed.
Parallel printing interfaces are nice when the printer doesn't
migrate much, but when you have a serial infrastructure over a
5000 sq ft building, serial printers are much quicker to
migrate (you don't have to move a card to move the printer).

P.S. - here's a thumbnail of the overstrike cat picture I was referring
to - http://www.threedee.com/jcm/aaa/images/catbig.jpg I must have been
dimly recalling John Foust's "Ancient Alphabetic Art" web page -
