    Bar code reader or some kind of remote receiver.?

    An amateur radio amplifier would be my guess based on the MC1590G and the power transistors.

    I think these are custom HP part numbers on the ICs.

    Near the upper left we have date codes of 8040 and 8114, and near the right 81xx, so I am placing it at the early 80s. Definitely not 2003ish.

    Looks vaguely like a TV pre-amplifier I pulled apart, much to my folks annoyance!

    This looks like a laser diode driver. However, the vintage of other components suggests otherwise.

    My guess that it’s an HP 10780A Laser Receiver, part of an older HP Laser transducer system.

    My first thought was that it looked similar to some of the older HP O-E converters I’d used for fiber optics stuff, but the MC1590 amplifier B/W was too low for that.

    That led me to look in the 1985 HP catalog at optical sensor stuff, leading to the 5501A Laser Transducer System and its’ receiver.

      It looks like you are almost certainly correct.

      Page 7-3 of your linked PDF contains both a B&W photo of the ware in question as well as the full schematic.

      Nice job! :-)

        Also worth noting are pages 6-1 and 6-2, which give the manual backdating instructions for older revisions; based on the changes seen between the two layouts, I’d say this is a 1644A prefix board, layout markup here:

          Earlier, I wrote:
          > I’d say this is a 1644A prefix board

          Actually, I’ve got that completely backwards-i.e. the board pictured in the HP manual looks like the 1644A prefix with the “change 2” backdating (remove C16, add jumpers), whereas the NTW board *has* C16, and no jumpers.

          That said, I think the NTW board might be a later prefix than any given in that 1948A service manual ( the 1948A would have R14=620 ohm, R17=180 ohm like the NTW board, but there also seem to be other PCB routing changes near regulator U3 )

            As it turns out, I had opened the wrong pdf earlier tonight, I was reading the ‘1948A’ prefix service manual instead of the ‘2204A’ prefix manual.

            The 2204A circuit description seems to match the NTW board- the regulator circuit was changed to use a 7805 instead of a 7810 at U3.

            (HP seems to never have updated their service manual’s picture-of-the-PCB for the later version manuals, but the schematic, BOM, and layout were changed)

    There’s an HP Journal article describing the 5501A system, including theory of operation of the 10780A receiver, here:

    http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1976-02.pdf

    Looking further at the PCB layout, there are some minor layout differences between the “A” service manual link I provided and the NTW picture, which could be either production changes or possibly a later version of the module- it looks like the 10780C and 10780F are still in production at Keysight today.

      Sam’s Laser FAQ: “Zygo 7080 looks similar to the HP/Agilent optical receivers but has a 7 pin LEMO connector instead of the funny 4 pin BNC”, Bunnies one has 4 pin connector

    I think it’s part of a tv or remote. I’m quite intrigued with the green bulb in the middle.
