There is an ARC X286 model12 286 LCC board available in good condition but there is a "small" problem: one of the PAL chips is missing.
Any chance of an image dump available somewhere or should I just skip this board?
Thanks.
Finding the dump is likely nearly impossible. If you want to start an andventure, and this kind of adventure is up to your taste, get the board, reverse engineer what the PAL is supposed to do and derive the required equations. Otherwise: skip it.
What's strange is that they left all the socketed ICs in place but removed that one PAL chip for whatever reason. Also I like this board because it doesn't seem to have an onboard Varta at all, just an external battery connector. I haven't seen a 286 board like that before.
don't most old ibm AT boards also only have an external battery connector ?
also seems like the cpu is missing 😀
Right to repair is fundamental. You own it, you're allowed to fix it.

I don't "do" IBMs, way overpriced for my taste. 😀
I have plenty of LCC chips & clips but only one working LCC board. Well, I gave this PAL-dump a chance but didn't expect much, I'll let somebody else deal with it.
Thanks guys.
