I have a Motorola RF-Audience! module with a GPS receiver
(disciplined time source).

I am not sure how to identify it....

Motorola 848504F01 P4, PTRN4307A, Copyright 1996, 4" x 11",
has an OnCore GPS receiver installed.

Front

LED's                                  9pin "D"    BNC
pwr 10Mhz GPS 1PPS       RS232        10Mhz


Back

9pin"D"  15pin "D"         BNC
Power    GPS/Timing    10Mhz

To make it more than a nice looking paperweight, I need:

1.  A manual, or at the least connector pin outs.

2.  Someone removed the OCXO.....

    a. part number and source at a reasonable cost to replace the OCXO...

    b. Has someone already hacked a HP 10811, or HP 10544 to this board?
