    There are many different kinds of PICs available in 8 pin packages.

    It wouldn't be much help identifying the PIC unless you have the code to program it with - which I presume you haven't?. If you're writing your own code, choose any PIC you like.

    You need to buy the kit from the guy to carry out the mods......

    This isnt the same as modding a playstation where the pics were 12C508s, the code was available and the wiring mods were all free.....

    Ahhh...takes me back a bit...( oeerrrr should I have said that.... )

    FWIW, you'd be better off just buying his mod kit, or anyone else's mod kit and proceeding to invalidate your warranty.....or perhaps not.

    There are quite a few 8-pin PICs around and even if you could identify which one has been used, regardless of his attempts to scratch off any identifying marks, it's quite likely that the contents (program) will be code-protected.

    A PIC is a microcontroller, which can be internally configured to perform certain functions, limited only by the hardware capabilites/number of IO lines available to that particular chip. Program code is used to configure the chip and tell it what to output in response to inputs on configured pins.

    As Nigel says, without the actual code that the seller is using, simply buying the same chip is useless. Useless, because buying that chip would only give you a piece of plastic with 8 pins that does nothing until it is programmed.

    HTH.

    It would be cheaper to buy an Xbox controller with rapid fire than it would be to modify one.
