The LNW supported four screen modes:
  • Mode 0 is the default TRS-80 screen with 64×16 characters, and 128×48 semi graphics.
  • Mode 1 is 480×192 monochrome.
  • Mode 2 uses high res graphics memory to colorize the mode 0 graphics. This results in 128×48 dots with 8 colors per dot. This mode could be used to 'colorize' the standard TRS-80 games when loaded with special software.
  • Mode 3 uses low res character memory to colorize the high res pixels. This results in 384×192 pixels on 128×48 color fields. Per color field a foreground and background color is selected from the basic 8 colors. The colors are white, green, yellow, red, magenta, blue, blue-green and black.


Company history

LNW started by making third party extensions for the Tandy TRS-80 model 1 market. They started in 1979 or 1980 with a System Extension, a D.I.Y. kit replacement of the Tandy Expansion Interface. The LNW80 appeared at the end of 1980. Later came the LNDoubler, a high quality double density adapter in 1981. 1983 saw the LNW II, an upgrade of the LNW80 capable of running CP/M and the LNW Team, which included an Intel 8088 board for MS-DOS compatibility. The company folded due to bankruptcy in 1984.
