    I need to track some of these down and i'm having trouble locating locating who makes them and what kind they are. of course they're germs, just having trouble pinpointing the specs. heres a pic of them, you can see their prints on each, and it looks like theres an X preceding the numbers on each one but are heavily rubbed off...

    They are Motorola devices, but it is possible those numbers were proprietry.

    It used to be common practice for equipment makers to have transistors & ICs supplied with their own part numbers rather than the 'real' number.
