    Not so well, unfortunately. While the iron on the bottom of the chips melted fine from the temperature, it had very little effect on the iron on the PCB... frustrating.

    Also look at the pics mentioned earlier in the thread, at the back of the card... the upper empty memory spot, look at the bottom part of it. See that missing resistor and burned lead? What could that mean?

    I made these images the first day I got the card, and it was there... I only noticed that when I started trying to solder the chip on the back (when I said that I compared it to a 9700 throughly, I was talking about the front... I only swiftly went over the back :oops:

    Anyways, I did a good clean-up job and the card works just as fine as before. I may try doing it again when I'll find out more about that burnt lead and have the time to... I'll try replacing all of the iron on the solder points on the PCB next time, that would take *some* time :roll:

    Actually, a burned lead may explain why all the other components are there. Maybe this was a card that was originally on the 9700 line, and somebody f'ed up. The mistake was deemed to not make it unsuitable as a 9500, and so it was sold as such. Speculation, obviously, but seems plausible.

    If true, it may mean that it will require a bit more work to fix, but I don't see why it wouldn't possible if you're that determined.

    Exactly what I had in mind.

    It kind of breaks my determination though, as the lead that's burnt can possibly be one of the inner PCB leads, which in turn makes practically whatever effort I apply pretty much useless.

    Got to investigate on that a little bit more, maybe it's not as bad... now where did I put that old voltmeter :)

    Sorry to hear it didn't work, I still tip me hat to you for even attempting it and for getting it back to working. 8)

    BTW-Your voltometer is in the back of your desk drawer. ;)

    :shock: You... how the... what... omg :shock:

    How did you know? :lol:

    On another note... very soon I'm getting a digicam, I'll take some pics of the cheap-ass equipment I used and maybe a short vid too :wink:
    I'll keep you updated, hope I'll get some more useful advice to make this mod work. Thanks for the heads-up so far :)

    It's where I always find mine when I lose it. ;)

    Tiny hijacking if you don't mind - can anybody please tell me what exactly those two ICs marked P15C-16211A are (data sheets, anyone)?

    I know of P16xxx parts, which is a temerature sensor with integrated logic, could be related...

    Just checked out that picture... wow :shock:
    I never even imagined that that's possible, and I see why you're asking :lol:

    Mmm, thanks. :D Are these used for signal level translation only (kinda hard to believe, since it's an AGP 1.0 slot), or is there some sort of MUXing/DeMUXing being done? What signal drives those OE pins?
