Hello. For sale here is a GMB-786UN Motherboard, 40 Euros plus postage at cost. I'm in Germany.
See manual here:
It's unusual in that it has an OPTi Local Bus socket (which never really caught on). It has a soldered AMD DX40 386 CPU plus a socket to upgrade to a 486 - up to a DX2-66. There is 128k cache installed. The same 486 upgrade socket can also be used for an FPU. Fortunately it had very minimal battery damage, you can see just a few darkened traces around the keyboard connector. I have not investigated them further, as it seems to work fine! The 1mb of SIMM RAM is also included. I've booted to DOS, everything seems to work fine, but I haven't tested further.
booted it to DOS, as you can see.
