CEM 3340 and SN76488 N... where are they now?

[James D. Goode]

Hello there. If you or any of your subscribers can assist me in locating a
few of each of these ICs, I would be most appreciative. I especially need
a 3340 for an old, prototype Paia kit called Hyperflange-Chorus that I
have. Any information on other CEM ICs that are still available would also
be great, as well as tips (or schematics, if you have them) on how I can
fix my Paia Gnome. Thank you very much.
