The Ware for February 2020 is shown below:
The case above contains two boards in a stack, so I separated them and took a photo of each to provide a little more insight into the ware.
Thanks again to Akiba for loaning me this ware to share!

Hmm, we have analog inputs, RS232/485, some Motorola MCU (MC6805/09?). Logo on the MCU sticker belongs to http://www.youngusa.com/.
So.. is it some remote weather station? Wind sensor?
A non-electronic clue is the case and dirt on it, that looks very IP65 so obviously something that’s seen quite a bit of outdoor use.
After looking around I’m pretty sure it’s a wind sensor interface. Exact model yet to find.
Hmm, my previous comment mysteriously disappeared, so let me write again – I’m quite sure it is a wind sensor interface from R.M.Young.
The terminals in the upper right corner go to the actual wind monitor. The terminals at the bottom of the PCB are most likely RS232 output (configured via jumpers).
That looks very likely. The logo on the Micro board matches their websites and the insulator colours and silkscreen wording match the wiring shown in the mechanical manual here.

A quick check through some of the other manuals makes the wiring harness for the mechanical sensors mostly the same
Well done ,Czajnick.
Well, I’m afraid I was too slow, and overlooked the type marking under the header pins. I’m not the winner here, not this time :)
Wrong! That’s RM Young 32500 electronic compass! Here’s the manual with screw terminals matching the photo: http://www.youngusa.com/catalog/pub/Manuals/Archive/32500-90(K).pdf

Is it some kind of industrial thermostat or control board?
R.M Young 46203 Temp Tracker?
hmm my earlier comment seems to have gone missing, trying again.
pretty sure it’s an RM Young 32500, but an earlier model without compass module.
found the company by searching the logo stuck on the PLCC, and it’s their only product I found with that case and two holes in the enclosure. The drawings in the manual match up quite well.
Also, I saw later that under the header it says Young 32520A :)
old manual here: http://www.youngusa.com/catalog/pub/Manuals/Archive/32500-90(K).pdf
also differs from the current version in the placement of calibrate switch/LED.
R.M Young 32500 Compass/Serial Interface.
There’s an R.M Young 32400 model as well.

Wow – that’s the first time in a *long* time I’ve seen a commercial product with socketed ICs. Really surprised to see it in a turn-of-the-century design.
I thought that practice ended by the 1980s, when the cost of the sockets often exceeded the chips, not to mention all the additional failure points they introduce.
Particularly given the amount of dirt and (presumably) moisture ingress via the grommets, socketing, as well as other things like the lack of conformal coating and other barrier protection is virtually asking for failures. I’ve worked with gear that had insect nests packed inside them and they still kept on going because of the extra protection in the ciruitry, while this looks pre-set for failure.
I’m not sure about the production volume, but can we consider it a niche product? Low volume / higher profit margin product can afford sockets, I guess.
Reliability is a whole different story, though :)
Those sockets are indeed very weird. Clearly it was built with a decent budget (hence all the LT parts), and I can believe that sockets would be good in an outdoor installation for repairability after (e.g.) lightning damage, but why in the world didn’t they use machined-pin sockets?
Looks like they bought the most expensive chips they could find and put them in the cheapest sockets they could find.
Well, you left the “Young” under the connector, and I know R.M. Young makes weather stations, and sure enough the logo matches.
And the 32520 under the connector matches what others have said higher up so I’m going to say they’re right :)
