The Domino is one of the first graphic cards for Amiga computers who were equipped with a so called 'Workbench Emulation'. This means that new screen modes are created by the driver software which then can be used by system compliant applications either in a window on workbench or opening their own screens without needing to be changed.

It was developed by Village Tronic on behalf of X-Pert Computer Services. The workbench emulation was developed by Thomas Sontowski (as far as known ¹⁾). The underlying liraries which contain the actual graphic functions were created by David Göhler and Klaus Burkert.

The card is a combination of a PC ISA bus card with a Tseng ET4000 graphic controller using 1MB RAM and a second board which contains the conversion hardware for the Zorro-Bus of the Amiga and a display switch.

The cards Digital to analog converter (DAC) supports 16, 256 und 32768 color modes as a plain frame buffer. A Blitter was first introduced for a later version (W32) of the ET4000 chip.

The picture on right hand side show a prototype with a 24 bit DAC on an adapter board. This version was never sold.
