Has anyone tried adding extra hardware to a VT100 to enable it to run CP/M using the terminal's own 8080 CPU? ;-)
Then again you could add a Raspberry Pi inside it that would emulate most systems of that era faster than the original hardware - not to mention being able to run BSD or Linux natively and fairly capably.
edit: apparently the VT100 has an internal "Standard Terminal Port" connector which you could plug expansion hardware into, like a PDP-8 or CP/M board... or a modern microcontroller board like a Pi or a BeagleBone:
