Following along this line of thought but also in regards all our

Would it not be possible to use something like a Blue Pill to make
a small board (small enough to actually fit in the CPU socket) that
emulated these old CPUs? Definitely enough horse power just wondered
if there was enough room for the microcode.
Blue pills are so yesterday! There are far more small-footprint MCUs
out there. More RAM than any Z80 ever had as well as lots of flash for
the code as well as pipelined 32-bit execution at eye-watering (relative
to the Z80) speeds.
Could it emulate a Z80? I don't see any insurmountable obstacles to
that. Could it be cycle- and timing- accurate? That's a harder one to
predict, but probably.
But I'd wonder what the point was. There are still lots of Z80s out
there in captivity.
