[sdiy] Looking for: AK Drummer (CRM-260) schematic

[Loscha]

Hi David and group

 I got one of these machines about 12 years ago
And it came with the following documentation.

I have a unit somewhere in my garage here in Australia.
It's missing the to half of the lid I think, but has all the circuitry
If it'd help you out, I can try and find it over the weekend and we can
arrange postage

Pretty sure this schematic will help!
