Except that every VT52 I've ever worked on used
semiconductor memory, not core.
Anyway. the fact that there's no microprocessor does not mean that
there's no software. There are plenty of microcoded TTL designs about
(the VT52 is one of them IMHO) which have PROMs containing something that
is reasonably called firmware. The Hazeltine 2000 is a 1972-era computer
terminal. It used core
memory, but did not have a microprocesor, and therefore, no
software.
So at least the Hazeltine did it in hardware.
As did the VT52 and a slew of others.
