HHC 2024: Forgotten Father of the Computer (Jeff Birt) 

This guy is everywhere! Saw him a week later at Tandy Assembly 350 miles away from this one! Nice job!

The first electronic computer was designed by Torres Quevedo, spanish inventor, and the name was algebraic machine.

Z1 used floating point, too. (I‘d probably call it mechanical - not electromechanical, since all that electricity did was shaft rotation by a vacuum cleaner motor). Thanks for bringing up the ABC - I was completely unaware

I thought this was a rhetorical question?

I’d like to know a bit more about the decimal to binary conversion at the input. It is probably not trivial since ten is not a power of two. Did ABC perform sort of long division by two?

Very interesting talk, many thanks Jeff (you spelt your name wrong!) cheers, Geoff

Hey Birt!
