Here is the datasheet for the display.
Note that company specific info has been redacted. |

These displays are pulled from units returned to the factory of a
major device manufacturer. (The don't want me advertising their
name or logo.) All units are tested for basic functionality before
shipment, but they are in USED condition and are sold "AS IS".

A prototype breakout board has been successfully tested and will be
available by the middle November. Another breakout board is for
sale as indicated in this
Parallax Propeller User Forum Thread. Note that my breakout
board and drivers are for 6-bit color, the same as the Parallax VGA
driver. In fact, the driver is just a modification of the VGA
driver. However, a breakout board with all 24 color pins brought
out is being sold by another forum member. |

The ExpressPCB schematic and PCB layout for the prototype breakout
board have been posted to the forum thread linked to above. Note
that an additional Vdd capacitor has been added to the final board for
