3D Glasses Adapter
The 3D glasses adapter uses a charge pump triggered by the Z80 Read and Write signals to generate a high voltage to drive the comparator which drives the 3D glasses. Thanks to kamillebidan on SMSPower.org for sharing the schematic. <a href="http://db-electronics.ca/wp-content/uploads/2016/04/SMS-3D-Adapter.png"><img class="aligncenter wp-image-191 size-full" src="http://db-electronics.ca/wp-content/uploads/2016/04/SMS-3D-Adapter.png" alt="SMS-3D-Adapter" width="740" height="380" /></a> There are two PCB jumpers found on the Sega Card PCB: M3 &amp; M4. These jumpers control which SMS signal connects to #CRDSEL (pin 3 of the 74HC259). <ul> <li>M3 shorted connects #CRDSEL to #CE (Pin 13 of Card Slot)</li> <li>M4 shorted connects #CRDSEL to #MREQ (Pin 3 of Card Slot)</li> </ul> <a href="http://db-electronics.ca/wp-content/uploads/2016/04/SMS-3D-AdapterBoard.png"><img class="aligncenter wp-image-192 size-full" src="http://db-electronics.ca/wp-content/uploads/2016/04/SMS-3D-AdapterBoard.png" alt="SMS-3D-AdapterBoard" width="693" height="390" /></a>
