Yes, DRIVER!! That was the best Easter Egg. You can play it here [1], Escape Control+6 after booting.
I loved that game so much as a kid. I made a clone of it as an entry to the IOCCC which won [2]. Sadly it no longer works in modern terminal emulators, but a slight modification [3] fixes it. Instructions here [4].
Aside, I got up to similar shenanigans in high school. Printed out "Y2K Compliant" stickers and stuck them on everything. My mother was a teacher so I did have access to a laminator ;) a privilege I left sadly underused.
