I don't know if RDR Electronics still have any X72's. There used to be a lot of X72's for sale that were pulled from something. They came with an adapter board that only broke out 16 of the 26 pins. I bought a couple... they had less than 1000 hours of run time on them. My signal board has support for the SA22.c rubidium, but I need to figure out how to connect to that horrid connector that is in the middle of the baseplate. I am also laying out an interface board for the Spectratime SRO-100 rubidium. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
