I recently acquired a 386DX-16 Industrial SBC by Texas Microsystems Incorporated (TMI). It is a typical full length ISA card that plugs into a passive backplane.
I am unable to find documentation or jumper settings for it, but that aside I can't get a keyboard to work with it.
In an AT-type passive backplane system, the keyboard connector is on the backplane itself, and I assume the controller is on the actual SBC. The system boots up perfectly but it always gives a "Keyboard failure" error. I have tried other keyboards and other passive backplanes but I can't get any keyboards to work. The capslock-numlock-scroll lock lights briefly flash when the system is powered up but that is all they do. I cannot toggle them nor does the keyboard work in any way. There is also a strange 8 pin power connector on the sbc with an unusual "double molex" ended cable, which I have no idea what is for.
Can anyone tell me anything about any of this?
Here is an identical card that sold on eBay:
