The part was an NTE replacement part, but those are usually relabled NOS 
parts (like the CA3080's I just bought - you can see the old markings below 
the NTE 996).

Yeah and I think you can do that with the CMOS version of the 555 - 7555 or 
TLC555.
If you wanted to you could make anything run on 1.5V - just make a voltage 
multiplier out of a 4011 or 4069 and some diodes and caps. You could even 
make it pretty small with tantalum caps and SMD's. A lot less smaller than 
another battery which would offset increased drain probably depending on the 
app.

But I digress...

What made me think about it was somewhere on the carrionsound website he 
mentioned making a version of the Lumivox with an LM3909.
