Title
Turbografx-16
Content
The Turbografx-16, originally known as the PC Engine in Japan, was the first console released as a 16 bit console though technically it is an 8 bit console. Don't like it - sue me! [toc] <h1>Technical Specifications</h1> #TODO <h1>Memory Map</h1> <h2>HuC6820</h2> The HuC6280 processor provides a 21bit address bus on the TurboGrafx allowing contiguous addressing of up to 2MB. The address space is divided into 256 8KB pages. [table id=7 /] <em>*size refers to the useful size within the range excluding any mirroring</em> <h2>Super System Card</h2> [table id=8 /] <h1>Video System</h1> <h2>Signal Measurements</h2> <h3>CSYNC</h3> CSYNC - 960mV p-p into 10K load <a href="http://db-electronics.ca/wp-content/uploads/2016/09/tg16-csync.jpg"><img class="aligncenter size-medium wp-image-803" src="http://db-electronics.ca/wp-content/uploads/2016/09/tg16-csync-300x169.jpg" alt="" width="300" height="169" /></a> <h2>dbGrafxbooster</h2> The <a href="http://db-electronics.ca/product/dbgrafx-booster-ttp/">dbGrafx Booster TTP</a> is a video enhancer I offer for sale which adds S-Video and RGB signals to TurboGrafx-16 / PC-Engine. <h1>EXT Port</h1> The EXP Port is located on the back of the console and is used primarily to interface to the CD Unit, <a href="http://www.geekvintage.com/nec-turbografx-16-turbobooster.php" rel="nofollow">TurboBooster</a> or the <a href="http://db-electronics.ca/product/dbgrafx-booster-ttp/">db Grafx Booster</a>. There are also RGB, composite video, and stereo audio signals found on the EXT Port which can be used to significantly increase the video and audio output quality. <table border="0" cellspacing="3" cellpadding="4" bgcolor="black"> <thead> <tr valign="top"> <th bgcolor="bbbbbb">1</th> <th bgcolor="bbbbbb">2</th> <th bgcolor="bbbbbb">3</th> <th bgcolor="bbbbbb">4</th> <th bgcolor="bbbbbb">5</th> <th bgcolor="bbbbbb">6</th> <th bgcolor="bbbbbb">7</th> <th bgcolor="bbbbbb">8</th> <th bgcolor="bbbbbb">9</th> <th bgcolor="bbbbbb">10</th> <th bgcolor="bbbbbb">11</th> <th bgcolor="bbbbbb">12</th> <th bgcolor="bbbbbb">13</th> <th bgcolor="bbbbbb">14</th> <th bgcolor="bbbbbb">15</th> <th bgcolor="bbbbbb">16</th> <th bgcolor="bbbbbb">17</th> <th bgcolor="bbbbbb">18</th> <th bgcolor="bbbbbb">19</th> <th bgcolor="bbbbbb">20</th> <th bgcolor="bbbbbb">21</th> <th bgcolor="bbbbbb">22</th> <th bgcolor="bbbbbb">23</th> </tr> </thead> <tbody> <tr valign="top"> <th bgcolor="bbbbbb">C</th> <td bgcolor="#ff9966">SNDR</td> <td bgcolor="444444"><span style="color: white;">GND</span></td> <td bgcolor="#ccccff">HuD</td> <td bgcolor="#00dcff">CEK</td> <td bgcolor="#e6ff00">A17</td> <td bgcolor="#e6ff00">A13</td> <td bgcolor="#e6ff00">A11</td> <td bgcolor="444444"><span style="color: white;">GND</span></td> <td bgcolor="#3deb3d">D2</td> <td bgcolor="#3deb3d">D4</td> <td bgcolor="#3deb3d">D6</td> <td bgcolor="#3deb3d">D7</td> <td bgcolor="#e6ff00">A1</td> <td bgcolor="#e6ff00">A3</td> <td bgcolor="#e6ff00">A4</td> <td bgcolor="#e6ff00">A6</td> <td bgcolor="444444"><span style="color: white;">GND</span></td> <td bgcolor="#e6ff00">A15</td> <td bgcolor="#e6ff00">A19</td> <td bgcolor="444444"><span style="color: white;">GND</span></td> <td bgcolor="444444"><span style="color: white;">Vout</span></td> <td bgcolor="#ff9966">Sync</td> <td bgcolor="#ff9966">Blu</td> </tr> <tr valign="top"> <th bgcolor="bbbbbb">B</th> <td bgcolor="#ff9966">SNDin</td> <td bgcolor="#ccccff">CDD</td> <td bgcolor="#ccccff">HSM</td> <td bgcolor="#ccccff">/WR</td> <td bgcolor="#00dcff">VU</td> <td bgcolor="#e6ff00">A8</td> <td bgcolor="#ccccff">/OE</td> <td bgcolor="#3deb3d">D0</td> <td bgcolor="#3deb3d">D3</td> <td bgcolor="#3deb3d">D5</td> <td bgcolor="#00dcff">HSn</td> <td bgcolor="#e6ff00">A0</td> <td bgcolor="#e6ff00">A2</td> <td bgcolor="#00dcff">VD6</td> <td bgcolor="#e6ff00">A5</td> <td bgcolor="#e6ff00">A7</td> <td bgcolor="#e6ff00">A12</td> <td bgcolor="#e6ff00">A16</td> <td bgcolor="#ccccff">A20</td> <td bgcolor="#00dcff">/RDY</td> <td bgcolor="#ccccff">IRQ2</td> <td bgcolor="#ccccff">/RST</td> <td bgcolor="#ff9966">Grn</td> </tr> <tr valign="top"> <th bgcolor="bbbbbb">A</th> <td bgcolor="#ff9966">SNDL</td> <td bgcolor="444444"><span style="color: white;">Vout</span></td> <td bgcolor="#00dcff">VS</td> <td bgcolor="#e6ff00">A18</td> <td bgcolor="#e6ff00">A14</td> <td bgcolor="#e6ff00">A9</td> <td bgcolor="#e6ff00">A10</td> <td bgcolor="#3deb3d">D1</td> <td bgcolor="#00dcff">DCK</td> <td bgcolor="#00dcff">VSn</td> <td bgcolor="444444"><span style="color: white;">Vin</span></td> <td bgcolor="#00dcff">VD8</td> <td bgcolor="#00dcff">VD7</td> <td bgcolor="444444"><span style="color: white;">Vin</span></td> <td bgcolor="#00dcff">VD5</td> <td bgcolor="#00dcff">VD4</td> <td bgcolor="#00dcff">VD3</td> <td bgcolor="#00dcff">VD2</td> <td bgcolor="#00dcff">VD1</td> <td bgcolor="#00dcff">VD0</td> <td bgcolor="444444"><span style="color: white;">GND</span></td> <td bgcolor="#ff9966">Vid</td> <td bgcolor="#ff9966">Red</td> </tr> <tr> <td colspan="24" bgcolor="white"> <table border="0"> <tbody> <tr> <td bgcolor="#444444"></td> <td bgcolor="white">Power</td> <td bgcolor="#ff9966"></td> <td bgcolor="white">Audio/Video</td> <td bgcolor="#3deb3d"></td> <td bgcolor="white">Data Bus</td> <td bgcolor="#e6ff00"></td> <td bgcolor="white">Address Bus</td> <td bgcolor="#ccccff"></td> <td bgcolor="white">System Functions</td> <td bgcolor="#00dcff"></td> <td bgcolor="white">Video Bus (?)</td> </tr> </tbody> </table> </td> </tr> </tbody> </table> <h1>HuCard</h1> The HuCard on PCe/TG-16 is a 38pos 0.050" pitch custom connector.

For a PCe, simply reverse the data pins (i.e. D0..D7 instead of D7..D0).
