A friend worked for a cable company over the summer and "procured" a "lost"
unit or two. (Shh!) They were of the new Jerrold series, though I have
forgotten exact models, et cetera.
Anyway, he gave them to me for inspection. They had a metal plate on the
back that, when removed, revealed a connector of some sort. I opened the whole
box (quite a trick, actually) and found that a small-ish (27128?) EEPROM seemed
to be rather directly connected to this interface. I never bothered to track
down pinouts to test the theory, but from this I guessed that the EEPROM could
be programmed / read from the interface, and actually stored a converter ID
number or similar. The system they were used on DOES send information signals
down the line, and an upgrade in service requires only a 15 second wait or so
while the operator types the authorization in, et cetera.
We cooked up this extensive plan to borrow a EEPROM programmer, take the
EEPROM from a box that was paying for all service, and make lots of copies of
it for ourselves and our friends. We WERE aware of the illegality of such a
thing..no flames, please.
So, would it have worked?? Are my assumptions on the EEPROM correct? Am
I more confused than I, myself realize??
