Scott Adams games 1-12 with ADVENTUR.COM version 8.4c, an interpreter for CP/M. Z-80 required because the random number generator depends on the R register. It has been tested on CP/M emulators that do implement the R register. Without the R register, the interpreter will hang after printing the first room but before accepting any commands. The interpreter program is believed to be identical to what was shipped on 8" floppy for CP/M, but it was copied from an MS-DOS-format disk of PC shareware made in the early 1990s.
