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:

Thanks in advance,

Pete
