Recently I've got an XT clone PC in very good shape, almost mint, dating from around 1990-91. For the moment I've repurposed the case to house an early 386 from around the same era since I cannot use or test the XT motherboard: I have no RGB compatible monitors and none of my VGA cards seem to be XT-compatible.
I've built myself an AT2XT keyboard adapter and are in the process of building an RGBtoHDMI using a RaspberryPi Zero so I can use the video card that came with the computer, but it will be a while before I get the PCB and necessary parts. So in the meantime I'd like to find more about the card:
It's made by Mitsubishi, model name seems to be "WEAL10", main chip is DC462312A and has 128KB of RAM and a 16KB ROM (attached). By the looks of it I assumed it's probably a monochrome adapter with a character ROM but was unable to find anything about the card of the chip, except for this thread in the VCF:
The poster of that thread seems to have gotten it from an XT clone that looks identical to mine, but has no additional info. Some people there also suggested it may be an EGA clone due to the amount of memory, but then the original poster seems to have given up and the thread died (I hate when that happens).
Any details or suggestions are welcome, especially any clues as to what the DIP switches and jumpers on the card may be for!
