The Graphics Gremlin is an FPGA-based ISA video card specifically designed to emulate certain old video standards. This initial release emulates the original IBM PC monochrome graphics adapter (MDA) as well as the original IBM color graphics adapter (CGA). Since the logic is defined by the bitstream loaded into the FPGA, new emulations may be available in the future to support other video standards.

The Graphics Gremlin an open-source project is designed by Tube Time

What is included

Fully assembled and tested Graphics Gremlin card with a 3D printed ISA bracket.

The SPI Flash containing the FPGA bitstreams is programmed with the Tube Time's code from November 20th, 2021. Newer code might be available from other sources. For example Aitor Gómez added Hercules Graphics and Tandy support in his fork of the Graphics Gremlin
