Infocom's Zork text-adventures for CBM/PET

Special thanks belongs to Edilbert Kirk for programming a Z-Machine-Interpreter in assembler. Supported computers are:

Saving and restoring of the current game status is possible.

There are two kind of interpreters for each computer: one for story files in Z3 format, the other for adventures in the Z5 format.

The interpreters for CBM 4032, 8032, 8096 and 8296 auto-detect the computer type, so only one executable exists for these computers.

Temple of Apshai

Temple of Apshai is a dungeon crawl role-playing video game developed and published by Automated Simulations (later renamed to Epyx) in 1979. Originating on the TRS-80 and Commodore PET, it was followed by several updated versions for other computers between 1980 and 1986. Temple of Apshai was the first title using the Dunjonquest gameplay system.

Though it was originally released for the Commodore PET, this version originates from a non-PET version which was modified by Edilbert Kirk to run on the PET again.
