I am working on my R4B crystal calibrator and the schematic doesn't show the
two ICs very well, used for counting down the 100 kc crystal frequency. They
are listed as a 923 J-K Flip-flop which are both no longer available. I think
NTE had them as a 9923. Does anyone have the 923 in a better more defined
description?
In the manual, the diagram for the calibrator doesn't show components either,
so the foil side of the board doesn't make it very easy to trace out the
circuit.
Garey, does your CD have it shown in a better more defined display someplace?
Thanks guys,
