Well, I couldn't sell JD while disclosing that it needs a new MPU so I have reluctantly decided to replace the MPU and try again. I plan to buy a new board with remote battery mount. However, it dawned on me that I have a perfectly good, totally unblemished one sitting in my TZ right next to JD. I mean it is original and spotless. Matter of fact I should think about updating ROM!

Would it make sense for me to put the existing TZ unit in JD that I plan to sell, and then install my new MPU in the TZ keeper?...OR, is there more value in keeping the pristine original board in TZ?

Thanks for your thoughts and advice.

Thanks...I will keep the board in TZ.
Agree that Chris would be a great option but he recommended a replacement after seeing pics in my prior thread.
Tough to spend another $190 on a machine that I will lose money on, but....so goes the hobby sometimes : )

Thanks for the input. Glad I asked.

Not sure if it is a good price and only tried local CL. I am way too honest to be a shrewd negotiator. I bought it for $1800 from another pinsider buddy. Good seller. I put about $50 in lock sets, new rubbers, lights, cleaning supplies, etc. so in for about $1850. I listed on CL for $1650 to compensate for the MPU goofiness. I would still take that if anyone is interested. May formally list it on here unless that price gets flamed..LOL
