286 MBoard Identifacation SMBO 1-1

[MauriceH]

Found in a box this old 286 CPU Board.

Like to know the settings of that switch block.
Can't find any options for this board.
Looked at the big listing of M-Boards on stason.org/TULARC
But not this one.

Does anybody recognise this motherboard?

Markings:
Made in Taiwan 1987 , SMBO I 1-1 , serial nr is A.T.E. sn number.
At the back there is the marking GX B-VO 8813

After using the just in house a PC-Analyser ISA Board I managed to get the MBoard going again.

What a great tool that PC-Analyser.
There was a failure on the -12V rail.
Due to a leaky Battery some copper lines were bad.
I already repair a couple but more had problems.

Then a Memory Error on one of the 256 RAM chips.
So replaced a few and it is running.
Not as it should, have to figure out the DIP-Switch settings, now I have 512K Instead of the placed 1024.

So Running and there is the BIOS.
286-BIOS (C) 1987 AMI, for CAC Computer Systems
America Megatrends Inc. S286-1108-110387-K7

Now we know the make of that MBoard.
