[time-nuts] Re: Kinemetric GPS-DC manual or information

[paul swed]

I am beginning to believe that the GPS-DC I have may be a model 1 or 0. It
has a single display. No sub display. A keypad and 3 black buttons under
the single display time, status, position. Serial number 76. Anyone seen
this unit? It looks like ebay 275352383003.
Thanks
Paul
