Can't Identify Issue

I am at my wits ends, I'm not sure what I'm doing wrong. I purchased the following items. GQ-4X usb programmer as well as the adaptor needed for larger eproms and flash eproms. I also purchased several am29f032b chips, and some TSOP40 adaptor boards both board type I and II. Soldered the chips to the board, the board to some pins but when I put it in the programmer it doesnt id. it just says ID check failed.("FFF7") I've tried several times but still each one I make fails to id.



Not sure what I'm doing wrong, could it be...

my soldering technique?

type of iron or soldering tip?

type of solder?

did i solder the wrong extra connections?

wrong set up on the adaptor board, am I suppose to move anything around for it to work with the tsop 40 boards?

    Someone earlier had the same issue: http://www.nintendoage.com/forum/messageview.cfm?catid=22&threadid=104858



    The software supports the chip, just not your adapter.

    I'm not sure if the issue is the same in the other forum post. I'm using this adaptor on my gq-4x http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4289 not the one the other was using that only holds the 29f032b chips that haven't been mounted yet. Mine I've already mounted the chips to adaptor boards. Is that a problem I thought I could mount them my chips to this board http://www.buyicnow.com/vp.php?pd=796 and this board http://www.buyicnow.com/vp.php?pd=1986, add the pins and program using the adaptor adp-054

    The answer as to why its not working is there. Its not the right adapter.



    "Device supported on ZIF socket:

    27C1024,27C2048, 27C4096,27C210,27C2002,27C4002,27C400, 27C800, 27C160, 27C322."



    29f032 not listed there.



    Not too savvy on snes flash chip repros, but if you look around, you should be able to find the right adapter for it.



    I think that other fella's issue was actually closely related to your own lol. 



    Good news is you might be able to do genesis repros with that adapter you have =0)

    hmm I had considered the possibility of having the wrong adaptor as originally I had bought most of the items on the assumption of programming regular eproms not flash ones. Does anyone know what adaptor I could use if the 29F032b eeproms are already on the TSOP 40 board? or is the only option to program them before hand on the ADP-077 adaptor

    Could someone help identify this adaptor image it came from a post on how to solder the 29f032b chips easily from this link http://www.mmmonkey.co.uk/29f032-soldering-dip36-to-tsop40-adapter-board/. I'm not sure if you can program using it but it seems to identify the eeprom and tsop which I can't seem to do. In any case I'd like to have it in order to test the eeproms and boards to make sure they're working

    If you ate mounting the chips first you must construct your own adapter.



    Also the one from the pic is the gq-3x adapter modified to work on 4x. It will program and erase buy will not verify properly. I believe I have a spare I can sell/trade made using the high end aries zif socket.
