A friend passed me the link to it, I got one, tossed it together, and it works
nicely.
http://dutchtronix.com/ScopeClock.htm
It has PPS input and NMEA parsing seems to be down the line.
The site only mentions Intel Hex. Are the sources available?
Not yeat. Seems that they will be as of V3.0 which I expect to pop up within a
month or so (he actually said two weeks, but as allways multiply with Pi from
what a software guy estimates in time).
It already has PPS input, but there is a little bit of a hardware hack to make
a proper 50 ohm terminated PPS. Not very hard thought, but needs an op-amp or
possibly a transistor with a few resistors.
Cheers,
Magnus
