Sounds like there's hope. It will be interesting to follow your progress!

So we finally got into the keyboard parts last night - just to give them a look. I haven't photographed anything yet but will do that once we unpack them for good.

KLM-367 (if I'm looking at everything correctly) is the board that is susceptible to damage from the battery leakage and it appears this one is no exception. We could see where attempts have been made to fix some traces. Time will tell if those attempts were successful. If not I suppose the Kiwisix upgrade would be the next solution since that apparently replaces this entire board (again, if I'm understanding everything correctly) but I will wait on that as it's a significant outlay of cash.

According to the original description I need to replace three switches - one is broken and two are damaged. And we need to replace two chips - one is $5 and one is $100.

All of the buttons are there except for one. Unfortunately not a single knob came bundled with the parts. The seller said he thought he had a bunch of them in his shop somewhere so I'll touch base with him on those because if you're actually lucky enough to find them they're annoyingly expensive. I'm sure there are other knobs that would fit and do the trick but I'd like to bring it back to stock as much as possible.

Also missing is the part of the chassis that houses the pitch and mod wheels - and those wheels are missing as well.

So basically I didn't learn much more by looking at the parts but after several weeks it looks like we're getting ready to ramp it up and that's exciting!

As posted elsewhere in the keyboard forum here we are also tackling a Prophet 600 that is in fantastic condition, besides a series of 8 keys that won't work. So - not sure what gets done first or how quickly, but fingers crossed we have some success with both keyboards.

I'll post more soon!

Not sure where you are in the world nickle15 but if you’re in the US, it might be worth contacting Syntaur to help you locate the missing parts you need.

Thanks Dan. I'm in the US and monitor the Syntaur site regularly. They seem like a really decent outfit and they're definitely on my radar. I appreciate the tip!

Sorry - I was just going off some notes my dad had written on a diagram. But it looks like the SSM2044.

Interesting chip. It wouldn't be easy to emulate that!

I wondered if it might be. It's possible I might have one; I'll check.

There’s somebody local to me selling two of these chips. He wants €45 each for them. If you get stuck and can’t find them in the US I’d be happy to pick one up for you and post it.
