    Replace the PLCC with an ISP part.

    Of course it is possible, especially if you value your time as
    $0.00/hour and are willing to spend $500 in components.

    But PLCC32 is a housing, not a particular chip. So exactly what chip
    do you want to program? Or do you have a DIP programmer and you want
    to make a PLCC adapter?

    im looking to program

    Amd
    AM29F040B

    here is a manual i found on it..

    http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/21445.pdf

    oh and the reason i dont want to buy a programmer really is because i
    have no use for it but just to program one chip..

    i was thinking of maybe using a cheaplpc programmer like the ones used
    to program the 32 pin xbox cheap mods but was told by someone it was
    not possible.

    , I thus relpy:
    From what it appears, the modchip for the Xbox uses an SST49LF020,
    which has the LPC programmability, while the 29F chip is exclusively
    parallel program, meaning you will have to make an 8 byte read/write
    bus, an up to 19 bit address bus, and the R/W/CE lines for it. Now,
    if you could, you could probably get the LPC version of the 29F040.

    If you are willing to work and/or spend money, you can build a
    programmer.

    Another option, if you are savvy enough, is to use a PC or other user
    upgradeable Flash appliance (Eg DVD player) and hot switch the roms
    at the right point,.

    You could also build an adaptor/ wire a socket to use the JTAG on
    something that uses that (such as a satellite receiver).

    Last resort would be to find a service that programs chips.

    You can build a flash programmer for the AM29F040 for about $50 based
    on circuit found at http://www.devrs.com/e/tools.php#toolprgr

    Select the link for "2001/07/09 - Frohwein-Sshua Flash Programmer"

    Modify the circuit for using a PLCC32 vs. DIP socket

    Make sure you use version 1.5 of software if you use 74HC595 chips.

    You may need to change BIOS setting in PC to make parallel port
    functional for use with programmer.

    Look into the BIOS flash programs for your motherboard manufacturer.

    Personally, I have been backing up roms using the BIOS extension
    socket on an old MFM HDD card, using Debug, or a Qbasic program (dos
    6.22 on a 386 though).

    Advertise for help on a local newsgroup.
    Go visit a university electronics lab.
    Ham radio club.
    Beg for help at a local chip distributor.
    You may have to make a PLCC to DIP adapter to use a generic
    programmer. You can buy 'em but you don't want to know what they cost.
