Folks, The TAPR GPS Kit documentation has been updated and revised for clarity (I hope). it includes details for purchasing end plates and also dimensions required to fabricate end plates. The TAPR GPS Kit document, and a motherboard schematic for reference, is now available on Synergy's "GPS for Scholars" page: http://www.synergy-gps.com/index.php?option=com_content&task=view&id=54&Itemid=73

TAPR archives all of this documentation, for discontinued GPS kits, can be seen on the left margin. https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.tapr.org%2Fgps_exp-kit.html&data=01%7C01%7Cart%40synergy-gps.com%7C4dc2f4b8f72f4e2fc73108d47615ead3%7Cc81f9fdec0e04d8c95779afaa0cad9ed%7C1&sdata=5ruapgEiQudgnwP07FQuZd1RF2r23b0YTZnMagdcLkI%3D&reserved=0 Tom Clark, W3IWI Total Accurate Clock (TAC) project (1996) covers the entire topic. https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.tapr.org%2Fkits_tac2.html&data=01%7C01%7Cart%40synergy-gps.com%7C4dc2f4b8f72f4e2fc73108d47615ead3%7Cc81f9fdec0e04d8c95779afaa0cad9ed%7C1&sdata=2ddW07UU31UDl5%2FQTy2DspkkX11FX00qrmKfc%2BRnNLw%3D&reserved=0 Simple interface board schematics (Serial Level converters, and voltage adjustments for external antennas/ 3.3 or 5 V) can be found throughout the Internet since mid-1990s. Numerous radio amateurs DIY their own (breadboard) or sold small interfaces at hamfests (1996-2006), until newer GPS solutions became surplus (and smartphones with built-in GPS appeared after 2007). Doug McKinney, KC3RL (SK, December 2006) offered interface boards for the Garmin (GPS-25) and Motorola receivers until about 2005. I have one of Doug's boards in my GPS parts box. These were sold by TAPR until their inventory was exhausted. -- Garmin https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.tapr.org%2Fgps_garminib.html&data=01%7C01%7Cart%40synergy-gps.com%7C4dc2f4b8f72f4e2fc73108d47615ead3%7Cc81f9fdec0e04d8c95779afaa0cad9ed%7C1&sdata=1rtHBUexr2FVGuHKY2qxBhzriCuFREe%2F6NAS7gi9RNY%3D&reserved=0 Motorola https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.tapr.org%2Fgps_vpib.html&data=01%7C01%7Cart%40synergy-gps.com%7C4dc2f4b8f72f4e2fc73108d47615ead3%7Cc81f9fdec0e04d8c95779afaa0cad9ed%7C1&sdata=R5%2FyBXV%2BAV2%2Fi3e%2BKfPlua5PKMhRqrbUwhIMPrbiArQ%3D&reserved=0 Synergy M12-MB board (web link to photo [jpg] below) IF you look closely at the Synergy Board, you see the board outline and 2x5 (10-pin) header for the earlier 8-channel Motorola receivers https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.tapr.org%2Fimages%2FM12-MB.jpg&data=01%7C01%7Cart%40synergy-gps.com%7C4dc2f4b8f72f4e2fc73108d47615ead3%7Cc81f9fdec0e04d8c95779afaa0cad9ed%7C1&sdata=VnOToRye%2Be6pu62p6Os1ohPVVa%2FzDEFh1%2F0vo%2Fi5ag4%3D&reserved=0 greg w9gb Sent from iPad Air > On Mar 28, 2017, at 12:18 PM, Larry McDavid <lmcda...@lmceng.com> wrote: > > What "OEM supplier?"
