Motorola offered an 8 channel GPS chipset and also a 12 channel chipset
based on the MC2003. A separate "RF Oncore" GPS receiver front end (PWA
Board) was also sold in the late nineties. These products were only
available to volume users (50 K pieces and up).

I'll review what we have stored in the Motorola archives. The problem is
that almost all of this early, legacy GPS receiver documentation was
only available in paper form.

Good to see some of that old material re-appearing.

Do you have any of the datasheets for the chips?

Cheers,
