I have this MB which I cannot identify. There is nothing printed on it, and also the BIOS string doesn't tell me much. I managed to reverse some settings

J9 - Reset
J29 - Keylock + Power On LED
J 26 - Speaker

There is an Intel R80286 10 MHZ CPU on it and 640 KB RAM.
Any hints on the remaining jumpers or a manual appreciated.

There is another problem however: None of my 16 bit ISA IO controllers seem to be working. It won't recognize them at all.
There was some battery leakage so it might be some disconnected tracks, but somehow I doubt it. Graphic is working.
