    Hi all-

    I'm hoping someone here will have the answer to all my questions, or
    at least this one. :) I'm looking for a closed loop control circuit
    for a dc motor that will sense both position and the speed of the
    motor. I have a schematic that uses three ICs, the L290, L291, and
    L292 that would do the job beautifully. Problem is, I can't find the
    L290 or L291 ICs anywhere. Does anyone know where I could find them,
    or if there is a replacement for either these two ICs or the entire
    circuit. Any information would be greatly appreciated.
