What a great talk, loved everything about that era.

When I was 14 I made my first virus/prank. It would increment a counter every time input was sent to the PS/2 port, ie. keyboard. Once it hit 2000 strokes it would switch to 80x50 textmode, print "This is a shareware keyboard. You have used all of your free keystrokes" and then close the PS/2 connection until a physical reboot.

I thought it was hilarious, but it did have some unintended consequences. Especially because that the IT guy in charge actually believed the message. So, also my last virus.
