Can't provide more info on the actual board, but it looks like a very late 486 motherboard (1996/1997) and from my own experience they are pretty bulletproof.

can anyone else find any info?

Some jumper settings here:

I've always been very interested in these ALD boards, because not many people had them. I think they came out at a time when everyone else had abandoned 486s.

Did you know the ALD chipset can supposedly do pipelined burst cache? At least according to the manual. The picture of the board you showed us is using async cache, but one time I actually did find an ALD board with the PLB modules fitted. Unfortunately it was already gone when I went back to buy it.

I believe they actually did make their own chipset, and the user manual should be on the website.

i don't know much about this so how to indicate cache modes? does it depend on different types of sram chips installed, or decided by the chipset? which type does common 486 chipsets(intel, sis, umc, ali, via) use? i can only remember that most socket7 chipsets used pipeline-burst cache.
