About the Game

Dive into the world of your very own PC's grandparents with Mainframe Men! Meet the handsome personifications of iconic computers like ENIAC as you explore the museum in this visual novel.

You've won a VIP ticket to the Computer History Museum's new exhibits. Soon, they'll show you just how interactive they really are...

Full game features:

  • Meet ENIAC, Mark 1, and other computers from the mid 1900s! (Who's this EDVAC guy, you ask?)

  • Learn about the museum itself, as well as the history behind the creation and legacy of these machines.

  • Learn what exactly binary even means, and how to translate it.

  • A few Bad Ends. (and one good one)

  • Increased boost in trivia stats. 

  • 50/50 shot of haunting your mind forever with guys who are wearing punch tape for clothes. 

  • Dialogue choices.

  • All of the normal visual novel features, skip, autoplay, save...

  • Get kidnapped?!?

  • Gain a souvenir.

  • Music and beautiful art!

While waiting for the full game's release, you can also check out our demo, which contains gameplay up to the end of Eniac's room!
