4107
The 4107 was one of three low cost color graphic terminals introduced at the Hannover Faire in Germany in April 1983. They were part of the "Unicorn" project which was to deliver a 4105 $3,995 color graphics terminal to the market in 18 months. The two additional products in the family were the 4107 640x480 resolution 13" color graphics terminal for $6950 and the 4109 640x480 resolution 19" color graphics terminal for $9950. The shipment for the 4107 and 4109 were delayed from the 4105 and the 4107 initially shipped on December 8, 1983.
Besides higher resolution, the 4107 and 4109 had local memory for segment storage that allowed local zoom and pan of the graphics data. All three terminals supported DEC VT100 alpha mode in a dialog area which could be turned on and off overlaying the graphics area.
The 4100 series of terminals were replaced by the 4100A series which added more memory and graphics editing capabilities. Two new terminals were added to the family along with a CX4100A family supporting the IBM 3270 environment. Later the 4100A series was replaced with the 4200 series of graphic terminals.
