NEW!! Improved Grafyx 4.2(.1) high-resolution graphics board for the TRS-80 Model 4 (26-1067,1068,1069), Model 4 Gate-Array (26-1068A and 26-1069A), and Tandy TRS-80 Model 4D (26-1070).

This is a new product based on the old GX 4.2 hi-res graphics board which has notbeen available since the late 1980s.

Mine provides the same 640x240 (153,600 pixel) graphics resolution as the GX 4.2 and Tandy's own 26-1126 board.

Compatible withmost currently released hi-res software from µLabs and DOSes which support hi-resolution programming like TRSDOS 1.3 and TRSDOS 6.01.02

Works in Model III mode as well as Model 4 mode.

Has proper full width 8-bit bus for superior performance over Tandy's 26-1126 with no "video snow" during fast graphical rendering.

Uses fewer chips, draws less power and generates less heat than the old GX 4.2.

Plugs straight in, no soldering required.
