A CXY08 is an eight-port multiplexer. Of course it doesn't
"multiplex" much of anything, but that's what they've always been
called. It's eight serial ports on a board.
As for what it's "good for", well, for connecting up to eight
serially-interfaced things to a PDP-11 or VAX.

Since I have some cables for one, I thought I'd go digging. These
links popped out...

I was curious about that... specifically, I caught that there's a
DHU/DHV-compatibility setting, but I was curious how far back there's
support for this board. I'm sure it'll work with modernish versions
of VMS, but what about PDP-11 operating systems? (most specifically,
I'd be thinking of RSTS and 2BSD). Anyone have any experience with
that? (My own is with older products on older machines, but except
for DZ11s and DLJ11Js, I think some of the older multi-serial
interfaces are less easy to find these days).

Wasn't the CXY08-M used in the DECserver 550 (or whatever it was called)? I
don't know if the OS's you mention support the board, but the DECserver that
used these had PDP-11/53 CPU's in them. I had a couple of the DECserver's,
but sadly had to dump them years ago. I kept a few of Serial boards and
cables, along with the other boards.

I have a pair of MicroVAX 3800's that came with one CXY-08 as they were
originally
used to collect process data from a variety of serial devices.
DECserver 550's came with 8 and 16 port varieties

A DECserver 550 is basically a M7554-SD KDJ11-SD, a M7516-PA DELQA-SA,
and one or more M3119-YA CXY08-M or M3118-YA CXA16-M, in a BA213 box.
I have a KDJ11-SD and have replaced its DECserver 550 EPROMs with
standard 11/53 EPROMs and have run 2.11BSD and RSTS/E 10.1 on and I'm
pretty sure I had no problem using both those OS with CXY08-M and
CXA16-M modules as terminal login connections.
I don't know if there are any programming interface differences
between a CXY08-M or a CXA16-M and an M3107 DHQ11. I think they are
basically equivalent.

Good to know in case I run across either a CXY08 or CXA16.

Excellent. Thanks for the confirmation.

Yes. I know nothing about the software that ran on those. I was thinking about
the more generic use of repurposing the serial cards with a more accessible
OS (i.e., one I use as opposed to a canned single-purpose application).
?I had a couple of the DECserver's,

A few years ago, I picked up a CPU board from one of these DECservers. It's
one of two KDF-11s I have (the other being a DECprofessional 380). I still
need to either drill out the handle or pick up a newer enclosure. I was
also contemplating seeing if I could fit it into my MINC on a temporary basis
(with the lid off) or an empty CompuServe "trinode" I have (a triple-backplane,
triple-PSU rackmount box that was once part of the CIS internal X.25 network).
Conversely, this CPU board is the only S-box board I have, but I know it's
easy to drop older boards into an S-box if I run across an enclosure.

That's coming in iOS 5! ;)
Sometimes I'd swear I'm the only person who changes the default
