I recently picked up this board which was in very bad condition, it's still dirty after I've used half a can of solvent on it 😀
Anyway, there's some damage up near the Y2/U18B area but it is still able to power on.
I get a blinking cursor but no VBIOS/BIOS messages.
The cursor/screen looks like it's in a 40 column mode (large cursor).
I'm trying to see what settings the DIP might need or any other jumpers but cannot find any sort of schematic.
Markings:
Chipset - TACT82301/2/3 PB Texas Instruments 3 chip solution
065-3.3-0789
8H-30513
OPC 94V0 1298M1 01-90 (on underside)
My google searches found a similar board made by "ComTec" but no other ID or model markings
