[time-nuts] SSR-6t Connector

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!
