I just had to replace the batteries on this one, so while it was open I tossed it in the scanner and figured it would make a fun and easy name that ware to start off the new year.

Also, there are two rows of pads around the bigger chip, I’m pretty sure it’s LCD display. The 93LC46 EEPROM might store some calibration data. And the bigger chip is most likely Samsung SAM47-series 4-bit (yeah!) MCU.
Bunnie – Did you scan this with a flat bed scanner? Way back in the days of parallel port scanners I had one with about a 0.75 inch depth of field. I could scan boards with components on and still have the board in focus even though it wasn’t down flat on the glass. None of the scanners I’ve had since have had any depth of field. If the object isn’t flat on the glass it’s not in focus.
And in fact, yes, none of the modern scanners have had any depth of field — I got a chance to tour a facility once that makes the sensors for probably 60% of modern scanners, and if you saw how they were made today it makes sense that they have no depth of field (light is piped to the sensors’ surface using a mechanism closer to a fiber optic, rather than a lens). But they are a lot, lot cheaper than back in the day.
The Cannoscan D660U is a relic — it has to be used with a virtual machine running Windows XP. I haven’t been able to find anything else that even remotely matches its depth of field, so I’ve held on to it through hook or crook…
I’ve had extremely good luck with recent Epson V33/V330 as well as the V600. They’ve both got about .75-1″ of DoF. Great for board scans, both still supported.
Back in the 90s I used to fight with a beast of a low-end SCSI scanner (that still cost me $1000) and had to do a gradient colour correction on because I didn’t know how simple it would have been to swap out the fading florescent tube… Anyway, I once had to scan a page out of a book for a job, and not being able to put the cover on, was surprised to also find in the scan the lights ceiling above the scanner, in darn good focus…
My old scanner had a parallel port interface and was from the days of Windows 95 or 98. It wouldn’t even work on Windows XP. I’ve kept it all these years on the chance that someday I could figure out how to make it work again. Maybe I could get it to work in linux. Or, I just found with a Google search that http://www.hamrick.com/ has software called VueScan that claims to work with old scanners no longer supported. I’ll have to check that out and see if it compatible with that old scanner. Would be nice to be able to scan objects like PCB assemblies again.
For sure some measurement equipment – REF02 form AD is 5.0V reference, there’s MC14447 8-bit A/D converter, AD8572 is dual op-amp.
Hmm, is it a double-input thermocouple thermoemeter? There are T1 +/- and T2 +/- markings near the connector at the bottom edge….

I’m going to say a TPI 343/C3 Water Resistant dual input K-Type thermocouple thermometer.
The picture is a spot on match for the case:

The connector, presumably to back casing with external probe connectors, with labels T1+- and T2+- also seems to indicate it is a *dual* thermometer.
Hmmm, this must be the first scanner I see that exhibits parallax…

Yep! It’s a Cannoscan D660U flat bed scanner.

What a coincidence.
I have a Cannoscan D660U under my desk that has not been turned on for years.
I was wondering if I should send it out to the e-waste pile, or see if it is useful.
Maybe I should start using it again.

Bunnie, it looks like there might be some more modern support for your Canoscan D660U here: http://www.sane-project.org
