Network Computing Devices
Network Computing Devices (NCD) is a company founded by Mike Harrigan, Doug Klein, Dave Cornelius, Ed Basart, Martin Eberhard, and Kevin Martin in the late 1980's to produce a new class of products now known as a "thin client". At that time these devices were known as network terminals or X Terminals. Judith Estrin and William Carrico joined the company about six months after its founding as its new CEO and executive VP, and led the company through its IPO. The products were some of the earliest examples of a thin client and providing remote access to data in something other than ASCII as was common with traditional terminals of the time.
The X Protocol provided a way to show high resolution images of data and graphics over a network connection. NCD supported a range of network protocols including TCP/IP, Token-Ring, DecNet and others.
