Dating an MP-1

[PrimalScream91]

I've been trying to date my MP-1 as well, I've got different numbers. In one place I see "2/87," and others start with 89. But up in the right hand corner, printed on the board reads:

MP-1  2-88
680075
Rev. E
asmbly 780OO2

So I'm not entirely sure about it.

You always have to take the youngest date you can find on the IC's.

The print on the pcb (last pic) doesn't matter for dating the mp-1.

Agreed. Just like trying to date a Fender Stratocaster, always use the newest date code to get the closest final assembly date.
