Throwback Thursday ADSL Modems: [Image of a Linksys ADSL modem showing DSL, USB, Ethernet ports, and power input] Before cable and fiber internet service was widely available, ADSL modems provided “high speed” Internet. Terribly slow compared to even wireless broadband today, it was a sophisticated way to compress more bandwidth into traditional copper telephone lines. vintage.computer

Wow That’s Fascinating The Internet Was Originally Called ARPANET Before the word “Internet” became household vocabulary, there was ARPANET—a government research project connecting a few universities and labs in the late 1960s. The first message ever sent? “LO”—an attempt at “LOGIN” that crashed the system. A clumsy start for what would become a global network. vintage.computer

TECH SPEC TUESDAY Xerox Alto [Image of a Xerox Alto computer] About this machine: The Xerox Alto was a tremendously influential computer. Designed by Xerox at the “Palo Alto Research Center” (or PARC) and released in 1973, it combined many standard-settings features in one extraordinarily expensive computer: $32,000! It had a custom micro-coded processor, a Graphical User Interface, a mouse, Ethernet networking including e-mail, file sharing, and network boot, and “What You See Is What You Get” desktop publishing. The Xerox Alto was seen as the future of computing in Silicon Valley.
