[time-nuts] Looking for a Trimble Lassen SK-8 or SK II 5V GPS receiver

Hi folks,

I went with plan “B” and am no longer looking for relatively recent Lassen receivers.

The clock using the older Lassen receiver speaks NMEA as well as Trimble protocols. I’m building a simple ExpressPCB board in the Trimble Lassen form factor to interface with a variety of more modern receivers. A few gates and a jumper enabled logic inversion now enable the clock to use most any 5V integrated antenna/receiver speaking NMEA or Trimble protocols at RS-232 or CMOS levels. 

Also found a pair of Garmin GPS18x LVC 5m on ebay which will be arriving next week about the time the bare boards get here.

Problem solved, correct date restored!

Many thanks!
