I am finally getting around to tackle my grid server unit, and could use some advice on trouble shooting one of the boards.
its a 3 board system ,a diagnostic board with a 8031 micro controller , a file server board with 80186 , and a com server board with a 80186
as far as i can tell there are no schematics or manuals for this beast.
The first problem i need to tackle is getting the com server board to be recognized by the diagnostic board. When the system is powered on the diagnostic board scans the buss for installed boards
and reports them. the diagnostic board and file sever board are recognized but the com server is not.
from visual inspection the com and file boards have the same basic interface circuits so that is good.the com board seems to start and run but i assume when the diagnostic board is requesting data from it the whole board locks up then goes back to running what ever its running.
My question is how would you go about tackling this ,with no schematic or information.
here is a screen of the boot up the com board is in slot 2
the errors are from no drives attached, that's a whole different issue for down the road
