True. Mea Culpa. I should have said, "the only Apple II bootable disk I
have is..."

On an early version of Zork I for the C-64, I managed to "give me to the
thief". Later on, in the strange passage, I saw "a cretin" sitting in
the hallway.

I remember seeing "Planetfall" up on the wall of the Digital Store in
downtown Columbus when I was a kid. I knew who Digital was, but I
didn't get my first Dec machine until I was 16 (a PDP-8/L that took
two years to restore owing to a lack of docs).

I agree. They aren't much different from each other, architecturally. I've
completely disassembled the C-64 version 1 engine, partially commented it
and gotten it running on VICE with a VIC-20 and a BASIC 3.0 PET! If I ever
had _way_ too much free time, I could probably craft a working engine for
RT-11. I used to program that for a living, too, in a former life.
