The VT1000 was a monochrome X Window System computer terminal introduced by Digital Equipment Corporation (DEC) in April 1990. The VT1200 replaced the VT1000 later that year, consisting of a code update and a bump in the RAM from 1 to 2 MB. All of the VT1000 series communicated with their host computers over Ethernet, supporting TCP/IP as well as DEC's terminal-oriented Local Area Transport (LAT) protocol. They also included standard serial ports to allow basic terminal emulation, built into the ROM.
Apparently unhappy with these VT1000s, DEC released the VT1300 at the same time as the 1200. This was essentially a cut-down diskless version of the VAXstation 3100 Model 30, allowing the X Window System code to be downloaded from the host system. An upgraded version of the VT1300 that allowed the host to download programs to the terminal to run them locally was the VTX2000, a concept DEC called an "X workstation".
