Congratulations! I remember Zork only available for the Apple, TRS-80
and Atari and all the nice write ups in BYTE. Though even after I got
it on the 64, I never got past that blocked mine tunnel.
BTW 4.0 PETs do some nasty things to cassette buffer #2, don't believe
it will stay just as you leave it..

15 years... Now I don't feel so bad about leaving my Light Cycles game
for about 10 or Flash Attack projects just as long. Though I think
programming on the 8-bits is gaining popularity again...
