Hello!

I acquired some small Digital thingies (SCSI terminators, connectors,
stuff like that), and I have some troubles identifiying them. The ones
with proper markings (Mxxxx, Hxxxx, BCxxx) are easier, but I have trouble
with the xx-yyyyy-zzz part numbers. Is there a source for numbers like
that out there somewhere?
Anyway, here are the gadgets I'd like to know better:
 H3104
 H3197
 H8574-A
 12-31281-01
 12-29258-01
 12-15336-08
 12-22196-02
 5019318
 17-01898-03 A01
 17-01835-01
 17-00862-01
 17-00286-01
 70-22313-01
 17-02659-02 (BC06P)
 17-00931-02
Is there a way to "decode" these values?

Thanks for the time!
