3.1 ROM upgrade

[spaceman88]

Just a quick update... After 3 emails to the seller, no response. Great customer service! I didn't want to solder the jumpers on the chip in case it didn't work and the seller claims I "damaged" it. I took apart my A2500 which has 3.1 and found an Escom 40 pin ROM chip, I removed it and put the 42 pin EBay chip in the 2500 and it worked. So I kept the Escom chip for the 500 and ordered a socket so I could do the soldering on it instead of the ROM chip in case I swap things around again :-). Thanks to everyone for the links and info about jumpers.

You can also just solder a wire on the bottom side of the a500 motherboard. You need to be careful plugging sockets into other sockets as depending on which one you order, you could damage the motherboard socket.
