  1. Hi, all--

    I picked up an old cable box at a recent hamfest. I'd like to use the
    tuner module as part of a receiver project.

    I'm fairly good at reverse-engineering things, but that can be a time
    consuming process. I wonder if anyone might have service schematics for
    this box:

    Jerrold Impulse CATV Converter
    General Instrument Corporation
    Jerrold Division
    Model DPBB 7312P/RI

    The tuner module itself has a sticker with the following information:

    LCMM (TAD)
    824-522-000 M H
    1217DA

    Please drop me a line if you can help. My email is:

    hpf (atsign) gainbroadband (dot) com

    Thanks in advance,

    Pete
