[time-nuts] SSR-6t Connector

Though the $35 special is only good for 1 unit per person,
Synergy offers a 10% educational/ham radio/experimenter discount for 
additional/subsequent units
bringing the price to around $63 for time-nuts who need more than 1. I'm 
thinking the other unit they have announced (without the PIC) should be even 
cheaper. Maybe if we are real nice they will offer a single unit special 
price on that one when it comes out early next year.

Had a good conversation with Art Slepin at Synergy. He said, if my
ancient memory serves, that the PIC on the new board will be available
for programming, and that it might be possible to do an ONCORE as a
software conversion from the UBLOX to the output connector. Just who is
going to do this, not sure. But it will be possible.
The newer versions of the SST will be programmable through the serial
port. At present, the extra side port on the board is a programming
connector.  The info will be on Synergy's SST website. Even at $70 per,
a UBLOX timer and PIC on the same board might be very cost-effective for
all sorts of fooling around!
