I would like to know if you can give me a hand to identify these motherboards that I found in an old warehouse of a factory. They are all tx-286 and a 386, the first board I looked for was JUKO ST, apparently it can do interesting things so I saw in the first google results on youtube. Unfortunately I do not have to try them, but anyway! The help is appreciated.

the fourth could be a variant of Hedaka HED-919 or a different model - the only 286 motherboard on that page with 8 short ISA slots.

I might as well learn something. I've seen 286 CPUs in many forms, but I've never seen motherboards where the gold chips could fit. they all look like >>61764739 and >>61764760 and sometimes soldered like >>61764786

also, are there specific tools to pull out the CPU from >>61764739 and >>61764760 ? the only time I tried by hand with a knife one pin was bent.
