That is correct. The Infocom games ran on an interpreter for
an
abstract machine called the Z-machine. Z-code is the Z-machine's
instruction set. There is a freeware implementation out there called
Frotz.
There's a reasonably functional Frotz implementation for TOPS-20, as it
happens. The ZIP interpreter was easier to port to 2.11BSD on the PDP-11.
