Need EPROM for Drake R8A

[steviewhite]

Hello, I need an EPROM for the Drake R8A Receiver. I bought it on Ebay and it appears it took a surge and corrupted the EPROM. I have bought one from the Drake Man on Ebay, but he has sent me 2 different checksums on the EPROMS he sent. They will not execute any instructions. All my waveforms look good on the processor. I would be willing to pay anyone who could copy theirs and send me a copy. There are no other places to get an EPROM, and I hate to let this receiver go down the tubes. Any help is appreciated, and an R8A manual would be a blessing too. Thanks. My Ham Call is NM8T (No More 8 Tracks) email: steviewhite @ suddenlink.net
