A small update here, I was looking for those missing 386 motherboards I bought a couple years ago. I went through another few stacks of motherboard boxes and finally found them, they apparently were send to me inside a single larger box and I think I might have asked this myself as sending the original motherboard boxes would have increased shipping costs. Kinda a shame, but I do still have the manuals (2 of them, I think I did get 3 (1 for each board) but I misplaced one of them).
The boards are brand new, the package was only opened by me a couple years ago so I could snip off the barrel batteries which already had started to leak.
The manual is labeled "CONTAQ-386 UPGRADABLE SYSTEM BOARD USER'S MANUAL" and the boards appear to be 386 ISA boards with both HIF sockets for 386 and weitek/387 and according to the manual, with some kind of special daughter board I can upgrade to a 486, but I don't have any of those.
It can run 40MHz and has cache sockets for (according to the manual) up to 256KB cache. Can't figure out what CPU speeds are available, but it has 4 settings which depend on the OSC speed, but I forgot to write that number down and I left the boards up stairs.
Strangely the first page of the manual staes a model number "MS-3124 Version 2.0", which reminds me more of the way MSI labels their boards (especially the MS-3???, MS stands for MSI I think and the first number always seems to always somewhat relate to the CPU architecture of the board).
On the board itself I read the chipset was a Contaq...something, but the manual lists the parts 82C206, 82C591 and 82C592 as the chipset. Will have to google those. The manual is very detailed, has pinouts and all that.
Now I know why I bought them, these boards seem pretty much awesome! Only thing missing is VLB and 72p memory sockets.
The manual is like it is brand new, I'll put "scanning 386 manual" somewhere at the top of my to-do list and upload it to Vogonsdrivers once uploading is made available again.
small edit: Apparently several other members here on Vogons got the same boards from the same seller, I'm reading up right now

Its written v2.1 on the CPUs aswell not only the fans, this dosnt prove anything though as it could be a guideline to what fan you should use.
I have tried the first new POD now, it works fine at stock speed but wont boot Windows 9x at 100 MHz.
I didn't even notice V2.1 was written on the fans, the "SL2RM V2.1" I noticed is visible on the CPU itself (all of the ones I removed the CPU fan from) after the CPU fan has been removed.
I agree, it doesn't prove anything. I'd be interested to know if other (Pentium) Overdrives have different 'numbers' here, like the DX4-100 Overdrives (which come with similar looking heatsinks, but are physically smaller) and the Pentium 2 Overdrives (which obviously are a lot larger as those are for s8).
Here are the pics I took. I know they're blurry but I don't have a working camera for now (I should really go see if I can get one cheaply).
