Alright, then I had it right then. Hmm...my soldering job was probably botched somehow then. I haven't soldered since high school! I went to Radio Shack last night and picked up a 25 watt iron, a small spool of 24-gauge wire, and a small spool of solder, so I believe all the equipment I bought is suitable. I assume that all the wire is run across the top of the chip i.e. the wire from pin 21 to 31 is run from the top of pin 21 to the top of pin 31, and the wire from pin 1 is soldered to the top of pin 1 and run across the top of the chip to the place where pin 31 would normally go. If that's not the case, then that would be where I messed up.

Please tell us you are using a wrist strap ground, or grounded workbench. It's amazing what static electricity can do!

I was indeed using a grounded workbench. I've learned the hard way about how easy it is to destroy a chip with a little static electricity.  :-D

Alright, I just received another 2.04 ROM, and I am about to try again with the soldering, but I'd hate to ruin another perfectly good ROM. Does anyone have perhaps a picture of what the final product should look like or something?

Well I attempted this again, and yet again it doesn't seem to be working. I put the chip in when finished, and instead of getting a black screen, or a red one, this time I get the first grey screen you get when it boots successfully. Unfortunately, it freezes here, instead of going on to show the other two shades of gray/white. Anyone know what I've done wrong? Perhaps I can still salvage this chip?

I'm not sure if my digital camera is working, but I'll certainly give it a try.
