My first computer.
It’s still around here somewhere...

Wow. I bow to your geekiness. I am not worthy.
My wife (EE) and I (ME) got a Commador 64 for our first Christmas together and spent Christmas Eve staying up until about 2am programming a PET character to bounce off the edges of the screen. No tape or floppy, though, so all our code disappeared when we turned it off. We knew it would happen ahead of time, but stayed up doing it anyway.
(Please see my tagline.)
Hope you have a great week.
