EEVblog 1705: Discover the World's First Desktop Personal Computer – The Olivetti Programma 101 (1965) 🖥️

The world's first desktop personal computer wasn't the Apple 1 or the Altair 8800. It wasn't even the HP 9100A, it was the Olivetti Programma 101 from 1965! Computer Teardowns don't get much more vintage than this.
