Couldn't find a part number on the .jpg of the gps rx to to cross
reference. Have a few +T's. Don't need another timing rx. Would take a
few positioning rx's as the M12+ units are good for balloon launches.
Reads out >65535ft.

>>> Interface Boards for Motorola (and Garmin) receivers have been discussed (and sold) by TAPR since late 1990s. TAPR archives all of this documentation, for discontinued GPS kits, can be seen on the left margin.
>>> Tom Clark, W3IWI Total Accurate Clock (TAC) project (1996) covers the entire topic.
>>> 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.
