Hi gang,

    Last year I purchased a bunch of Heath equipment.  In one box which was postmarked Dec 26, 1974 was a circuit board with the number 85-1521-1 on it.  It has a power cable going to the board and it is marked 6.3 volts AC/DC.  It has a 4MHz Crystal, a double flip-flop circuit to divide the frequency to 1MHz and then 3 decade counters to provide 100 KHz, 10 KHz and 1000 Hz.  What was this used for?  Some sort of a calibrator I would think, but for what?  It also has the correction sheet for page 8 in the manual.

Thanks

Dwight
