Datapoint 3300 gets it’s name because it was 100 times better than the Teletype model 33.  In 1974  Vic Poor directed John Murphy to create a networking standard that was plug compatible with the first Datapoint Terminals.

This stunning Datapoint breadboard prototype was discovered in a box from San Antonio, TX  where it all started and stopped for the pioneering company.   In the pictures we plug it in to a Datapoint I/O port.   Also included is a finished product – a MSI logic Datapoint 8-port coaxial hub.
