LNW-80
A 1982 computer built by LNW Research / From Wikipedia, the free encyclopedia
The LNW-80, released in 1982, is the first computer built by LNW Research Corporation (later known as LNW Computers).[1][2][3] 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 an 80×24 screen, with a special software driver (TRS-80 is 64×16, while 80×24 is the screen size most CP/M software needed). Other enhancements were high processor speed (Z-80A at 4 MHz), color support, and optionally, CP/M support. The LNW-80 was also sold as a kit.[3]

The LNW supported four screen modes:
- Mode 0 is the default TRS-80 screen with 64×16 characters, and 128×48 semigraphics.
- Mode 1 is 480×192 monochrome.
- Mode 2 uses high-resolution 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 eight colors. The colors are white, green, yellow, red, magenta, blue, blue-green and black.
