That's cool, but your [1] seems to say that the machine uses a wafer 12.5 mm in diameter, which is is probably less area than any of the CPUs in your [2].
Maybe not comparable in die size for all the chips mentioned there, i don't care so much, because i don't want to clone or emulate them. I want to go simpler. Rebranch from the 70ies so to speak, to take all the roads not taken since then. Just to see what's there :-)
That's 122mm², which is larger than some Pentium II dies, so if you're okay with designing to a circular die[0], you could fit a Pentium II-grade CPU on each wafer.
0: The main reason to use a rectangular die is that they tesselate better to fit many dies per wafer.
