What kinds of programs were available for this machine? I’m really curious what kind of complexity was it capable of running.

https://en.wikipedia.org/wiki/Bendix_G-15 is the computer that has been restored.

His excitement is infectious. It's hard to not feel giddy at seeing it finally run after all that hard work!

I can't wait to see the kinds of programs we can run on a machine like that, along with discussions about tricks when writing programs for serial memory computers :D
