It was intended to provide high resolution (at the time) monochrome graphic abilities to computers limited to text displays. It was aimed at the business market and one of the three first third party graphic boards for PCs (the others being Plantronics Colorplus and Hercules Graphics Card).[3]

It offered a monochrome 720 × 350 pixel resolution (similar to Hercules Graphics Card)[4] and required an existing MDA board to function.[5][3] The board also offered an IBM PC joystick adapter.[5]

No software, other than GSX-86[6][2] and that supplied with the board (Dr. Halo by Media Cybernetics),[7][8][3] offered support for the hardware. Graphic routines could be called from FORTRAN, PASCAL or IBM BASIC.[5]

Output capabilities

  • 720 × 350 monochrome graphics, pixel aspect ratio of 1:1.55.
