The Data General Eclipse line had a feature called "Writable Control

Floppy?
It was a real huge 8" flop ... (still have them here)

Yep. There was an LSI-11 (microprocessor version of PDP-11) hidden in
the cabinet, equipped with one or two 8", hard sectored drives. It was
also used to connect the console terminal. As I recall, the command to
use it as the VAX console was "STP" and Ctl-Z(?) to return to the LSI-11
console. Back in it's day, the VAX was considered a "super mini", a
real hot system. But it only had the CPU power of a 386!
BTW, that's where I first came across the "Adventure" game. :-
Several years ago I was given an Xerox floppy drive with a box of 8"
floppies. Many "commercial" programs. Unfortunately I didn't get the
computer that went with them. The lady that owned it had already given
that to a school for challenged children to hammer on. *<[:o(
as in, with large blunt pieces of metal on wooden sticks?
