Museums always seek historical context, so there it is. Big Grin

Absolutely! Does anyone still know exactly how they were discovered? They're not mentioned in the manual as far as I remember, they don't appear in the function catalog and they don't appear in the matrix menu either. Did someone have access to a ROM listing or something?
