I've got a whole bunch of boards that fall into a couple of different
"categories" of what they look like. I've got a few different types of
HP boards and some "unlabelled manufacturer" boards (the DC1127
pictures). Note that I've probably got better looking boards on
average than these; these are just the ones off the top of the pile
that were easy to bring inside.
The pictures are up at:
http://computer-refuge.org/classiccmp/pics040216/
I'm going to guess the HP boards are labelled by the part number of the
machine they go in; the 09885 are for a 9885 and the 02116 are for a
2116? And before you go asking me for the boards, stop. I'm not going
to do anything with them until I know what they are. : )

So does this mean no one has a clue what any of these are?...

Not exactly.
<http://computer-refuge.org/classiccmp/pics040216/HP-09895-66500-end.jpg>
looks like a HP 3000 board but the 9895 PN >>indicates<< that it's for
the
HP 9895 disk drive. The "FDU" might mean Floppy Disk Unit so it tends to
support that too.
<http://computer-refuge.org/classiccmp/pics040216/HP-02116-6119_H_741_6.jpg>
and <http://computer-refuge.org/classiccmp/pics040216/HP-12604-60001.jpg>
appear to be boards for a HP 1000 computer. You can check the PNs against
the manual on Al's site. Are there any mrkings on the pull tabs of those
two cards?
No idea on the 1127 boards.

Let's see, Mr. Holmes....
The DC1127 is clearly marked (fuzzy photos notwithstanding) "Dual 8 Bit
Latch" on it's reverse.
Might be a dual 8-bit latch of some kind...
The 66500 board says 'FDU Control' - Fixed Disk Unit? it has addr and
write enable switches... looks like a late 70s - early 80s era HP disc
I/O - for embedded test - network analyzers - ???
The rest of the photos are so badly lit and out of focus that I can't
make out the designations - on the 6119 board - there is a crystal (the
oblong tin can) in the upper left corner - above that is some writing -
what does it say?
Might be some treasures in here - also might be some gold scrap - some of
the boards have the 3-RU form factor HP used in a lot of their
early-digital era bench gear...

It's the text in the file name:
(HP logo) 02116-6119
H 741 6
On the handles are "TIME BASE GEN" and "A".
For the other similarly shaped card (12604-600001), there's labels stuck
near the part number that say "1046A" and "03142" and on one of the
handles is printed "HP DATA".

Hmm.

That's what it is then, a Time Base Generator for the HP 1000s. It was
used for the same purposes that you'd use a clock/timer circuit for in a

I'm not sure what that is. My guess is that it's a data interface
probably for something like a PT reader or punch or maybe the I/O expansion
chassis. But again go look at the HP manuals on Al's site.

The board "HP-02116-6119_H_741_6" is identical in form,layout and bus
connections (as far as can be discerned from the photo) to the time base generator board
in my HP 2116C computer, although the part number in the upper left corner of my board is
different (12539-60001). According to the manual for the 12539 from Al's site the
12539 is for the 2100,2114,2115 and 2116 computers. There seems to be some confusion
between the 'interface kit' number and the HP part number, perhaps the version you
have is earlier, for the 2116 and before the 2100 existed. (My 12539 is from ~1971,72
based on the IC date codes.)
It is, as Joe said, a programmable timed interrupt generator.
Many of the ICs on the board are (obsolete,difficult to find(?)) CTL logic as per
discussion of several weeks ago.
Given the 16 transistors/component sets on the "HP-12604-60001" I'd guess
it's a 16 bit I/O port or dual 8-bit I/O port (also for the 21xx machines).

New subject: Complete! Re: Help needed identifying boards
It appears that the DC on the DC1127 (and other boards I've got) stands
for "Department of Chemistry." Aparently the "Instrument room" at
Purdue's Chem department used to make a lot of their own boards for
custom instrumentation before off-the-shelf instrumentation was readily
available. I'm not sure what I want to do with them yet; I'm
considering making schematics of them and possibly making "something"
out of them. Of course, that probably won't be for a while...
The other boards are indeed HP 21xx boards (and the 9885 and 9895
boards). I've got a list of the boards and probably will be offering
them for sale/trade soon... I've got a few people that I want to give
first dibs to, but they might end up here.

No definite information. Sorry, don't have a lot of time to do
research right now.
Your 02116 board looks like it is made to fit a 21xx of some sort.
9885 is a single 8" floppy drive in a box, and came in two flavors,
9885M being "master" with controller and able to have up to three
9885S "slave" drives connected.
9895 is a box with room for two 8" floppy drives, and I think had an
HP-IB interface so would have an internal floppy-disk controller.

Yeap, the 9895 replaced the 9885. It used DSDD disks and held about 1.4
Mb per disk IIRC and it was HP-IB.
