I was dumping trash at my local recycler. They only accept paper, cardboard, and glass...and people leave things there that they cant recycle legally.
The other day I found a General Instrument Jerrold 450 model DRZ-3DIC.
What can I do with this box? Can it be hacked? I am assuming it is an addressible converter. It initially would not turn on, the power switch and channel up/down switches were broken from hard use...they are the small
metal disk that "clicks" much like an old atari joystick used to use.
I figured out the matrix (not hard) and replaced the power and +/- switches. There were only five switches used (cable a, b, channel +, -, on/off)
out of a 20 switch matrix. Anyone KNOW what these other switches do?
Any info you can give would be appreciated.
Dont bother flames. Even if I find out how to hack this box (like get a
test chip to replace the GI PIC 1655XT-290) I dont think Ill bother. I already have one for a Tocom, and I dont use it. Its the KNOWLEDGE thing... where all TRUE hardware and software hacking is based!
