Day 2 and it's mostly back together and working. I ordered a service manual on eBay, and expect it to arrive after i'm done. Oh well.
The floppy disk drive is from an ancient Atari 520ST computah. It works, but is too high to fit in the floppy disk drive bay. It sits on top of the case, upside-down, with the ribbon and power cables dangling out of the front of the DSS-1. Ugly, but functional.
More photos of the guts.
To do: Find replacement screws, fix FD drive, make plastic kbd cover.

My Korg DSS-1 was giving me enough trouble to justify a general cleanup and rebuild. Opening the case revealed plenty of dust, dirt, water damage, corrosion, rust, dead bugs, jungle rot, stale beer, cola, food debris, staples, paper clips, and some really digusting mold. Not unexpected considering it hasn't been cleaned since I bought it in 1992. During the process of disassembly, I also discovered that some of the screws were missing. Much of the time was spent gaining access to buried boards, and cleaning with 409, a paint brush, and air compressor.
Disassembled. The long strip on top of the keyboard are the keyboard contacts. It's held on by about 30 small screws. Most of the mold and mess was on the top of the contact board, which meant that it had to be removed to be cleaned. 409 cleaner, clean paint brush, and compressed air to blow off the suds and water.
Same as before, but viewed from the right side. When removing the various keyboard connectors, you'll find that all of the connectors are identical and really easy to get mixed up. I used a colored marking pen to identify the plugs and corresponding jacks. Nail polish or wire labels would also have worked.
More, but with the keyboard removed.
