Gentlemen, What you have is a Motorola SL Oncore navigation receiver, R6 series model number, with timing firmware installed. These 8 channel receivers, slightly smaller than the UT+ but larger than the M12x receivers, were flashed with UT+ timing firmware and shipped to various telecom companies between 1999 and 2003.
Unlike the Motorola VP, GT/GT+ and UT/UT+ receivers, the SL Oncore receivers are characterized by an "RF Dam" PC trace in place of the full metal shield covering the RF components. Most of the SL Oncore receivers we shipped were mounted in a full, shielded enclosure to operate in higher EMI environments encountered in telecom installations. An "SL Oncore Engineering Notes" document outlines the physical, electrical and environmental characteristics of this GPS receiver. A separate User's Guide for the SL was not published. The navigation firmware load is like the older GT+ and the timing firmware load is like the UT+. Therefore, the UT+ command/reply messages outlined in the GT+/UT+ User's Guide can serve as a reference to the timing messages available in the SL Oncore. Because of continuing requests, we will be updating our web site to include information on Motorola's legacy GPS receivers. In the interim, please let me know where I can e-mail the SL Engineering Notes so that anyone with interest can make reference to them. Engineering notes in electronic form are also available for the Basic Oncore, VP Oncore, GT+ & UT+ Oncore and the M12 Oncore (but not M12+) - Thanks!

Thanks Christian, I have that doc but although I think it is probably relevant the outline of the pcb is totally different to the pcb I have though more like a number of M12 Oncores I have. Thank you for your interest, and help.
