Anybody got a sheet for a Texas Instruments TMS3874 digital clock IC ? Loads
of references on the 'net, and people claiming to be suppliers and having a
datasheet, but you just finish up getting led down the path to companies in
China, with no sign of the actual sheet ...

Just the pin-out will do if nothing else available. It's a 'rescue' project
for a very old mate, so not desperately important, but it would be nice to
get it going for him again, as it was an apprentice piece that he built 38
years ago, and it has worked all that time until last week, when it just
suddenly stopped. I'm loathe to believe that the IC itself has failed, but
you never know ...

I know at one point I looked up some clock ICs in the NTE replacement
guide, and found what I was looking for. So checking one of those might
provide the pinout.
