[sci.electronics] Looking for a Fairchild 3817DPC Digital Alarm Clock IC.

I am desperately looking for a Fairchild 3817DPC. It is a 40 pin
PMOS IC with alarm, sleep timer and 4x7 segment LED driver builtin.
Basically, it is a clock radio, minus the radio. It has been obselete
for at least 10 years. My broken one has a 1975 datecode on it. The
last databook that I found it in was the 1975 issue of Fairchild MOS
Integrated Circuits in the Consumer/Industrial section.

I have had no luck tracking one down from local suppliers.
(Surprise, surprise.) Is there anyone from National/Fairchild who
knows anything about this IC? Might there be one sitting on a shelf
somewhere?  National has no outlet here so I have been unable to
determine if any still exist. Has the chip been superceded by another
part? It seems to provide all the functionality required for typical
clock radio, so something like it must be available.

As the clock has sentimental value, I am willing to pay any reasonable
price for one, even if it is used. I will probably even grudgingly pay
an unreasonable price. (BTW, what is a reasonable price for such a
relic?)

If you know anything about this IC, or know anyone who might, please,
please let me know.

Thanks.
