[time-nuts] Datametrics Clock

[Dave Brown]

Looking for an ancient Signetics divider to get this operational. The 
power supply issue I mentioned in a previous post is sorted and with 1 
MHz input its now generating 1pps etc just fine. But I need an 8288, 
divide by 12, TTL, 14 pin DIL to replace a dead one in the 
accumulator. Might be able to bodge a 7492 in place of, but will lose 
the preset capability-and would have to patch an inverter in as well 
to match up with existing decoder drive polarity.  All in all, much 
prefer to just plug in an 8288!
Seems like they are now as bad as the proverbial rocking horse 
excrement. Anything out there?
