Howdy Folks,

I was "gifted" a Frederick 1200 FSK Demodulator.  It has a terminal strip 
and two Molex connectors on the rear.

I figured out terminal strip 1 & 2 are audio input....it responds to 2125 
and 2975 when I sweep it with an audio oscillator.

The Molex pins have some "activity" on the ohmmeter/voltmeter.  It looks 
like one Molex might be an RS 232 and a Mil 188 output....just a guess here.

Can anyone tell me the terminal strip and Molex assignments.  I cleaned out 
all the wasp/muddabber mud, resoldered "tinkered" components and think it 
might now be "serviceable".

Any info is sure appreciated,

Lar
