While I was looking to find a manual for a 486 motherboard which I recently purchased on eBay, I stumbled across this resource: https://www.infania.net/misc/moboarchive/index.html
It might be known to you, but I have never before seen such a tremendous archive of everything motherboard. I tried to back it up with sitesucker for Mac, but after downloading approximately 7GB it crashed. For those of you into very early 286 and 386 motherboards, check out this link: https://www.infania.net/misc/moboarchive/Oldm … m/mb/index.html\
Please, if you have the appropriate software try to download the entire archive and upload it here. This treasure should not be lost!
