Just a heads up on another topic: a unit from 1988 might not incorporate the hardware fix for the start-up problem.
If you ever see the MP-1 sometimes not booting up when powered up, you will know.

I'm pretty sure it is stock with no mods done at all. Just went over the two ADA Depot noise mods (v1 & v2) and couldn't identify any of the mods on my MP1. This unit is from 1988 and marked as revision D (it also has the 1.38 software)
