  care of it. For example, reading core is destructive,
that is 
 it erases the contents so you have to store the contents back 
 into it before you do anything else (unless you don't care if

 ld be easy enough to do in HW but I don't know if that's 
 what they did. 
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...
