I just recently purchased a defective old PC-1600. Turns out I got a great deal as the auction price was low, and when I received it two days later, I find it to be in excellent physical condition. The exceptions being that it wasn't operable, and when I opened it up, I found substantial battery corrosion which had been eating away at the traces on the board and some of the components. I did end up repairing some of the smaller traces which had corroded closest to the holes. Just some simple jumpers with solder. Still not working after I assemble it. Go back and start replacing components with the most corrosion on their leads. Still not working. Finally after two more tries and replacing a diode and 7 resistors, I got it working. I've already purchased the 2.3 EPROM and non-volatile SRAM as upgrades, just waiting on them. I plan on using my PC-1600(X) with two Matrix-1000's, D-550, DX21, Rebirth, SoundDiver and possibly everything else I have.
My big question is how do I load these patches into my PC-1600X? Do I need a Windows machine with a sequencing program to load them in? I'm running ProTools on a G4, but I do have an old PC laptop to use if need be.
