Jim,

Forgot to add two things. There were two versions of the system - the rack mount had 6 slots and the portable had 5. And the rubidium oscillator is an Efratom FRK.

I have the -01A module controller, -02 freq comparator, -03 freq generator (500MHz), -04 digital delay gen, and -20 clock module. I haven’t seen one with an 18GHz plug-in; that would be nice.
