This blog seems to indicate that there is NO 7074, but an emulator

This makes a lot more sense, some of these microcode emulations were
still available of fairly late machines. Also, it probably would not
be real hard to write a decent emulator for the 7074 and run it on
modern hardware. Once you are using emulation, why not keep the host
hardware current?
Too bad the excerpts from the original talk are totally scrambled.
It wouldn't surprise me if the IBM S/370 isn't being emulated as well.
It wouldn't be the first time for "nested" emulation.
Is there a "recursive" emulator setup wherein one machine emulates
another one...where the final emulation is for the original hardware?
