The Computer History Museum tracks the history of computers from 1945 to 1990 and beyond. I was most entertained by their computer time-line. That’s where you can see the computers that started it all (way back in 1945!). I also saw many of the ‘putes I’ve worked with over the ages including:
The Commodore PET
I did find that they are missing many of the computers I used in my early days, but it was still a fun walk down memory lane.
