This Oberheim Synthesizer Expansion Module had been modified to the extreme, with over a dozen holes drilled in it for switches and jacks (did I mention that I’m anti mods that are harming to appearance, undocumented, and make the unit unreliable?). It no longer worked, and the circuit board and connectors had been damaged. The mods were removed (see tray of junk) and the unit put back to standard as tracks etc. were repaired, and things put back to where they should be. I made a cover piece from Formica to cover the holes in the case, and obtained the correct power switch and jack. The unit was then re-capped, set up, and is finally back with Jim, its proud owner.
