About this episode
This episode explores the unique features and history of the Olivetti Programma 101, a distinctive early computer.
The Olivetti Programma 101 isn't quite like any other machine. On first glance it looks like a big desktop calculator. Inside, it's a purebred computer... but strange one. It uses twisted spring steel for memory, has no addresses, and it's machine code looks more like a spell than a program. It's existence is due, in no small part, to a man being very mean to GE engineers. Like Advent of Computing? Then check out the after show!
