When digging through my old boxes I found some 486 cpus I didn't even know I had, but they look like they have different numbers and sizes of pins. Looking at the Wikipedia there seem to be several sockets that take 486 chips [socket 2/3/4 at least].

Is there any cross-compatibility between these [so that one cpu might fit two or three socket types] or do I have to get a board with an exactly matching socket type?

Socket 4 is a Pentium socket, the correct sockets are Socket 1 through Socket 3 (and there was the imaginary Socket 6 😜 )
I think it depends for a great deal on the motherboard, mainly if the board supports other voltages then just the standard 5v CPU's

i also wonder if there were any socket6 boards made for PC(not for industrial or nec)? it has official definition for 60 and 66 fsb, and i wonder which chipsets had support for that, although some boards with umc chipsets were known to run at that speed.

I think there may have been a Japanese NEC PC 98 system that used socket 6.
