I am playing Time Zone for the Apple II, but I can't go to South America 1000AD. I put Disk 5I in, which is the disk that has the SA time period, and push [Return] but nothing happens. I tried both AppleWin and MESS with the same result, and the disk that I am using is Time Zone (1982)(On-Line)(Disk 5 Side A)[nib] which seems to be the only copy of the disk.
