The LNW-80 is the first computer built by LNW Research. The computer is 100% compatible with the Tandy TRS-80 Model 1, but has some hardware enhancements. Most notable are the high-resolution color graphics, which could also be used for a 80x24 screen, with a special software driver (TRS-80 is 64x16, while 80x24 is the screen size most CP/M software needed). Other enhancements were high processor speed (4 MHz), color support, and optionally, CP/M support. The LNW-80 was also sold as a kit.

The LNW supported four screen modes:

  • Mode 0 is the default TRS-80 screen with 64x16 characters, and 128x48 semi graphics.
  • Mode 1 is 480x192 monochrome.
  • Mode 2 uses high res graphics memory to colorize the mode 0 graphics. This results in 128x48 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 384x192 pixels on 128x48 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.

LNW-80 model II Edit

There are references to LNW having made a second Z80A based system called the LNW-80 Model II. This machine
