A friend gave me a dead synthesizer (keys broken) and in it I found two socketed ICs:
M112B1 ZC85206P
Both are 40-pin DIP packages. I have learned that the M112B1 is a polyphonic synthesizer chip. I'm curious to find the datasheet for it. The other is a Motorola chip but I'm not sure what it is.
85206, Note the excess zero removed, gets you Mesa, AZ, but NOT where the "Motorola complex" is located. The Motorola facility is west of Loop 101, 85206 is several miles EAST of Loop 101.
(85026 is in downtown Phoenix, nowhere near any Motorola site.)
Of course the standard question is, "What would Phil Allison know?" ;-)

I love to cook with wine. Sometimes I even put it in the food.
It's very likely a custom, mask-programmed microcontroller of some kind, and the numbers are house numbers. Ignore the crack about the zip code - Phil's pulling your chain.
Unfortunately, there's not much you can do about getting a replacement, unless you call the service department at the place the unit was bought from.

** In attempting to find some info on the OP's " ZC " number, I put the digits and the word "motorola" into Google.
The first few hits showed the number was the zip code (ie ZC) for a nearby suburb ( Mesa) to Motorola's main facility.
Too complicated piece of co-incidental humour for you to get your pointy head around - Jim ???
