[Mr TUBEAMPS]

i have a faulty modul
im looking for a chip part no-PIC0-78570
i cannot find it in any lists that i have
is there a nother number or matching
chip. the chip has 18 pins.there is another number on it
its 8936.

john!

The last number is the date code...36th week of 1989.

The chip is going to have to come from another module
since it is an OEM version. What module is it from?

It looks like a PIC. I don't know for sure when X10 was defined but I'm

betting it wasn't as early as '89, nor would the PIC have been produced
then. I agree the replacement will only come from a similar module.

Well, there ya go! It's also possible that they used a custom IC which just

happened to have the prefix 'PIC' too. Either way, replacement from another
unit is pretty well the only way to go.

Cheers.

I don't recall when General Instruments became Microchip, the maker of the
PIC but 1989 would seem about right as does using a PIC as an X10 receiver/
decoder.

PICs were designed in the early/mid 70s (you can tell from the dated

architecture), Microchip was spun off from general instruments in
1985-ish.

X-10 has been around since the late 70's. PIC's have been around,
pre-Microchip, since the early-mid 80's. Can't remember when I first
started using them, it was pre-Microchip, and between 1984 and 1988.
Microchip was fully established with their own fab by 1989 IIRC.

It sounds a bit like an old mains modulator chip, the number rings a bell.

I guess you could send out any code and make polyphonics as well, but to
make a bell sound wouldnt you be better off using one of those old telecom
ones in old phones, they make a nice bell sound when struck, I suppose
you could rig up an X10 decoder but getting the hammer strength just
right could mean some PWM stuff and then what do you do with the
waste power - back emf - do you send it back down the line with
an X10 ack to say there is a back emf pulse on the way ?

peter purple for a reason
