    I have a bootrom chip and I wish to make a copy.

    Can you guys point me in the right direction please ?

    The chip is a 43 pin PLCC square shaped.

    It has the following written on it

    12C1 L

    How can I identify the chip and purchase a similar blank chip to copy
    it onto ?
    Which burner can I use ?

    Thanks !

    Actually, that would be 44 pin. There's no such thing as a 43 pin
    Are you sure it's an EPROM?

    Is there a manufacturer's logo on the part?
    Totally dependent on what kind of part it is. I can certainly
    handle PLCC's with my own hardware (see my other response to your other
    message), but I'm not sure what you've got. What equipment is it out of?

    Keep the peace(es).

    Thanks for your response, actually I left out an important details, the
    chip says
    M27C4001 on it.

    It's out of a Cisco router, it's the boot rom.

    I would like to know how I can make a copy of this chip and which cheap
    burner and
    chips I can use ?

    Thanks for you help
