Dean,

Just call SuperChips up and tell them what happened. I suspect that they will, if anything, just charge you for the cost and shipping on a new EPROM ($10-$20?)....which isn't that expensive. What you're really paying all that money for is the coding that's burned into the chip. They may want you to show receipt of purchase or if you don't have it, send them the EPROM.

As far as repairing pins....forget it. Even if you solder back on, which IS possible depending on where it broke, once you put it back in the socket it will break off again either immediately OR at the most inopportune time.
