Even though the version 2 of the EPROM modification was developed for the VA62A, it can be used in the VA62. So before I describe the operation of version 2 of the EPROM modification I want to show the installation of the version 2 EPROM into the VA62. Here is how
1. Open the VA62 as described before and remove the EPROM. Solder a small wire (I used a 30 gauge wire-wrap wire) to the pin of the CPU as show in this picture.
2.
3. Bend the pin of the EPROM shown up, so that it will not be inserted into the EPROM socket. Solder the other end of the new wire to this pin. You may want to bend the pin, with the wire soldered to it, so that it does not interfere with the socket so that the EPROM will fully seat into the socket.
If you have a VA62A, then do not add the wire as it is already part of the circuit board. For a VA62A you just plug the version 2 EPROM into its socket.
Next I will describe the operation of the version 2 EPROM modification.
