I wonder how far back you can go? Could a modern chess engine run on a Cray 1? 386? 68k?
I don't think there's a meaningful difference between the Pentium and the 80386 except speed. You might have to change the compiler options a bit.
And, with more work, that's true of computers in general; they can all do the same computations once you somehow wire up enough memory: https://dmitry.gr/?r=05.Projects&proj=35.%20Linux4004
