Reply to comment by Dexta57 in TIL that at its peak, GEOS (Commodore 64 productivity software resembling Windows/Office and MacOS) was the third-most-popular microcomputer operating system in the world in terms of units shipped, trailing only MS-DOS and Mac OS by Profile_Salty

In the mid-1980s we had PET computers, the forerunner of the C64. I ended up writing an interactive program that simulated a fake login into the school district mainframe where it simulated allowing you to change your grades, just like in War Games. A few laughs were had with several groups of gullible kids. A few people freaked out over it. Fun times.
