Board 5 for me please. I have lots of motherboards but not a 386/486 one. Are these known working?

Edit: after visually scanning all the socket 2/3 motherboards at TH99 I think this one is a Silicon Star International AT4 http://arvutimuuseum.ee/th99/m/A-B/33565.htm

And as stated below, the extra socket is for a Weitek NPU, not 386. I think the only true 386/486 board in this lot was #1. I'll still take #5, boards with Weitek sockets are pretty rare too.

The second socket on boards 4 and 5 would be for a Weitek 4167.
