    I have a bunch of electronics that were stored away carefully and I am trying to identify them but I need some help. I have two pieces that are circuit boards (?)---- with a bunch of pieces on it---and the identifying information on it says: UHF Generator, 112.875 MHz H(2) also says Isotemp Research Inc, M431260 (the other one has a different set if numbers following the M).

    I have had no luck googling it, but my dad was an electrical engineer so they were his...

    The other piece I am having difficulty identifying is another (smaller) circuit board (also has a bunch of pieces on it) and it says O/P Distribution Amp. then it says SMG (in an oval) -5-0. Any help identifying these pieces would be GREATLY appreciated, because google is not cutting it! Thanks

    Where is the Isotemp information located?

    My guess is that it is a 4.13260MHz crystal oscillator, perhaps oven-controlled.

    Why are you trying to determine what these are? It is very unlikely that they are worth anything. You might take them to a local ham meeting (amateur radio club) and someone there might have a good idea both what they are and whether they might still have some value.
