Bless you kind sir for correctly deciphering my second question! The part number does indeed check out as the original 128k board and I had no idea that my guess was so correct! All I had before was a guess, now I have expert information. Thank you again for deciphering my question in the way I was trying to ask it-I just didn't know it took "THAT" long to start producing 128k/512k hybrid boards, rear buckets, and serial numbers. I appreciate you so much enlightening me that my guess was correct!

God bless you and have an EXCELLENT day for living up to your well-earned name!
