Cheetah MD-8 Manual - Help

If anyone out there has a manual for a Cheetah MD8 or knows anything about how to dump the voices over MIDI using Sysex then please let me know. This feckin machine is driving me mad!

Obviously it can't be circuit bent seeing as it has the most volatile non-volatile memory i've ever seen but all i want is to stop having to load the voices in off goddamn tape. Well, i say tape, what i mean is WAV files of the tape data but after you've tried to load in a snare sound 20 times and its just not working because the input volume needs to be minutely adjusted to get it to work it starts to feel like this technology is just to obsolete to work with.

And i never thought i'd say that about anything. Angry
