<p><b>New page</b></p><div>The P-ROC is capable of directly driving a Dot Matrix Display (DMD) through a 14-bit ribbon cable. Supported DMD features include:<br />
<br />
* Programmable resolution, including 128x32.<br />
* Up to 16 brightness levels (colors)<br />
* 48 kb frame buffer storage (3 full frames @ 128x32)<br />
* Frame events (for software synchronization)<br />
<br />
Note: The P-ROC does not supply the electrical power for the DMD. The DMD must be powered by other circuits/supplies. If you're using the P-ROC to replace the CPU board in an existing machine, then all you need to do is hook up the 14-pin ribbon cable since the existing DMD gets its power from the existing machine's power supply. If you're building a new machine, you'll need to power the DMD from your power supply in addition to making the 14-pin ribbon connection to your P-ROC.</div>Steveshoyer
