Any suggestions for BY914, BY918, S1, OA70, OA79?

I just scored some of these off somewhere.  Any ideas on what i could do with them or build with them?   trannys=BY914, BY918, S1  Diodes=OA70, OA79

OAxx sounds like some Ge diodes, you could try them in any diode clipper circuit.

Never heard of those transistors, google doesn't give any results either?! :?
Do you know if they are NPN or PNP?

Have no clue.  I got them in a lot I won that had 10 OC44 and 2 OC71 and 10 OC72.  So I'm just trying to figure out what I can do with them. :?
