    Taking apart an old CDI ignition system to revive it, am having
    trouble ID'ing a Fujitsu 14-pin DIP.

    PN is MB4213

    Any help much appreciated

    BTW, it had a slightly-harder-than RTV potting compound that yielded
    nicely to a heat gun- it got crumbly when heated, returns to being
    tough when cool.

    While I can't help you ID that part, I will say that experience has
    taught me that the hard to find/test or otherwise exotic part in a
    device is rarely the problem. Did you check all the simple stuff first?

    My 1st goal (pure curiosity) is to group the parts into the main
    subsystems- I'm pretty sure they are a 12VDC to 100VAC (or so)
    inverter, an RPM sensor (built out of discretes), an advance
    mechanism, power storage section, and of course the trigger that
    shoots the juice to the coil.

    Probably the RPM/advance stuff is something clever, a few discretes
    and probably the IC.

    Hi Dave...

    Google MB4213 and you'll get several hits... hope that one or
    more are helpful.

    Take care.

    My google-fu is fair, but alas, none are matches.

    I believe this was prob. an OEM inly part.
