Lexicon PCM-60 V 1.0 eprom

I recently purchased a PCM-60 and fixed it.  I runs fine now but the eproms are the second revision that changes the "hall" preset for a "reverse room".

While I've never heard the hall preset I'm sure it's more useful so I'd like to find the V1.0 revison eproms.  Some people sell the V2.0 on eBay but don't have the original eproms for sale.

Does anyone have access to the PCM-60 V1.0 eproms, or can point me to a seller or an image online.

The only other solution I see is to buy another and swap or copy them, but I was hoping for an easier solution.

thanks for reading
