It came through fine as an email attachment, cheers for that.  ;)

I've uploaded the Manual and the WAV file of the sound data here if anyone needs it: http://www.mediafire.com/?u9d83bjkj850sfy

I actually spoke to one of the original Cheetah design engineers about this a while back and his response was something along the lines of 'its a piece of crap, it never worked properly'

Make of that what you will. I ended up selling the only MD8 i've had through sheer frustration at nothing working the way it should. I never managed to get anything other than the most basic functionality to work right, certainly not any kind of sysex dump.

I don't think its going to be an EPROM problem and i very much doubt that even the original designers have a copy of the data file. Why would anyone keep it? I'd imagine the only place to get a copy of the EPROM would be from someone whos got one with a programmer to read it.

The MD8 is such a piece of junk there could be dozens of things wrong with it. Check the internal backup battery for leaks and look carefully for dry solder joints and cracks.

I think the battery is actually missing on that board, which might have something to do with the problems you are having. That would indicate that someone has removed it as it was leaking. The brown stuff around the pins on the chips and the damage to the tracks on the bottom left of the first photo would certainly suggest a battery leak.

From the look of it the battery was meant to solder into those three empty holes on the lower left where something has obviously been removed.

I wonder if you could replace the sample RAM with a ROM chip?

If at first you don't succeed, stick it through a fuzzbox.

Does anyone still have the Manual and samples for this?

Rapidshare doesn't work these days.

Thanks for any help :-)
