Since I understand that hardware made by Data Translation is sometimes
used in psychological experiments, I thought I'd see if I can get in
touch with users of such equipment through this newsgroup.

For the curious, Data Translation makes analog to digital converters
(and visa versa), and they make packages containing such converters and
associated computers.

Anyway, I bought a Data Translation box, model DT4253-Dr, SN 5051, at a
surplus sale because it looked like it might hit the landfill if I
didn't, and now I'm trying to find a home for it, or more likely, someone
who can use the pieces as spares for old Data Translation or DEC PDP-11
hardware they might be using.

I'll get rid of any or all of it for shipping costs plus whatever you
think it's worth to you.

Here's what was in the box (and also the box, for that matter):

  1) A Q-bus backplane (H9275A, 9 slot quad), in rack mount enclosure with
	power supplies, fan, and front panel with reset and power switches.
	This is really a nicely packaged system!

  2) I also have A Q-bus backplane (DDV-11B, 9 slot hex), left over from
	another surplus purchase (I needed the rack mount slides).

  3) DEC M7270 (KD11-H) LSI-11 (PDP-11/02) CPU.

  4) DEC M8186 (KDF11-A) PDP-11/23 CPU (missing an option chip, the MMU?).
	Someone bid $50 on this, conditional on CPU revision level,
        so you may be out of luck.

  5) DEC M8044 BB Memory.

  6) DEC M8028 (DLV11-F) EIA or Current Loop serial board.

  7) DEC M8043 (DLV11-J) 4 channel EIA serial board.

  8) DEC M8016 function unknown, but might have something to do with power.

  9) Texas Instruments TMM10010-01 Q-bus mem. board, ASSY 1700150-02, SN 0705.

  10) Data Translation EP057 Rev J, SN 72421-317;
	function unknown, but has 40 pin berg connector, 10Mhz crystal.

  11) Data Translation EP125 MCP Rev D, P/N 02181, SN 68452-306, quad height.
	Has DT5712 analog mux and analog to digital converter module.

  12) Data Translation EP075 Rev F, SN 73682-301.
	Has DT212 12-bit digital to analog converter module.

  13) Data Translation EP058 Rev F, SN 76622-329.

  14) LSI 50 Alloy Eng CPD, SN 5115, quad height.  Function unknown.
	Has 40 pin Berg connector.

  15) Scientific Micro Systems Prog Assy 1001939-0001, Assy No 0003770-0001,
	SN LE8056, function unknown, but could be ROM.
	Has 40 pin Berg connector.

All of the boards had been pulled from their original slots in the
backplane by the time I got to the pile, although I think all of the
Data Translation cards and most of the others came from the
Data Translation box.

I'd appreciate any advice I can get (by E-mail) about finding a home for
this stuff.  At the worst, the stuff is good for parts, but I'd guess
that much of it is still functional.  If you want anything, you'll have
to pay postage (UPS surface delivery).  If you expect there to be
competition for a part, make me an offer above postage.  I'll send to
the highest bidder, but don't write a checks for more than the postage
until you see if what you get works, since I don't know if any of it is
any good.  I don't want any of it back, though.
