Ah, old memories. A quick google search brought up:

Should give you some information on the chip. No idea of where you
could get one, though.

I think it's another opportunist, via google groups.

It sounds like he's finally going to try to get the keyer going, and if
he can't, he's offering to sell the IC to the previous poster, who I
guess was looking for one.

Since there isn't much more involved than the IC, I'm not sure how one
determines that the rest of the circuitry is at fault (but can't be fixed)
but the IC isn't.

But since he didn't quote the message he was replying to, and the original
message must be quite old, who really knows?
