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.

When you'd turn it back on, it usually lost some bits, but you
would always bring up the last screen that had been displayed,
if someone didn't explicitly clear it. Not the kind of terminal
to use in secure installtions...
