I did some digging, and it doesn't look good for System 7 or 68k Macs. Apparently the earliest version of AppleScript that supports the "Delay" command is AppleScript 1.3, which only loads on Mac OS 8.5 or later, and is 99% PowerPC native so it won't work on a 68k Mac! This means we have to figure out another way to run the main script on a timer, if it's going to work on anything below Mac OS 8.5 or on 68k. Perhaps a separate "program scheduler" application? (Maybe Cron Manager)

Not looking easy, lol.
