Portable Teletype: The computers of 40 years ago filled entire rooms and yet had less computing power than today's smartphones. But the dream of portable computing was already alive. PC World contributing editor Harry McCracken recently uncovered evidence of that aspiration in the annals of Google's Computerworld archives. In March 1968, you couldn't carry a computer around with you--but you could take your Teletype interface, thanks to the Teletype Corporation's KSR-33. This little number dented the scales at 65 pounds, but it let users connect to a Teletype machine--a device for sending typed messages from one location to another--far from their home base. You can watch (and listen to) a KSR-33 terminal at work in this YouTube clip.
