Orchid Graphics Adapter
The Orchid Graphics Adapter is a graphics board for IBM PC compatible computers, released in 1982 by Orchid Technology.
It was intended to provide high resolution 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.
It offered a monochrome 720 × 350 pixel resolution and required an existing IBM [Monochrome Display Adapter|MDA] board to function. The board also offered an IBM PC joystick adapter.
No software, other than GSX-86 and that supplied with the board, offered support for the hardware. Graphic routines could be called from FORTRAN, PASCAL or IBM BASIC.
Output capabilities
- 720 × 350 monochrome graphics, pixel aspect ratio of 1:1.55.
