I have always liked the way this keyboard looked. I finally picked one up on ebay, it arrived and this is what I ended up with. Doesn't look so bad, lets open her up: Okay, quite a bit of rust on this thing. It is extremely crusty and much of the insides are sticky with some sort of beverage. I cleaned the case, set it aside and got to work examining the back of the motherboard. This is stock soldering: The board has some obvious water damage that goes hand in hand with the above rust issues. The board feels slightly "expanded" in parts. Similar to wet particle board that has expanded and then dried again.
Lets de-solder the switches and see whats under there: Bag o' switches (what is the ID on these?) Like I said above the board had a "soft" feel to it. Several traces did not survive the de-solder job
