JavaStation
The JavaStation was a Network Computer (NC) developed by Sun Microsystems between 1996 and 2000, intended to run only Java applications.
The hardware is based on the design of the Sun SPARCstation series, a very successful line of UNIX workstations. The JavaStation, as an NC, lacks a hard drive, floppy or CD-ROM drive. It also differs from other Sun systems in having PS/2 keyboard and mouse interfaces and a VGA monitor connector.
