I once tried to convince Kawai that they send me the logic equations of
those two CK2605 PLAs inside the K3m. Just wanted to spare me
desoldering them and reading them out myself (they can't be protected
like modern ones). Also the table EPROMs are soldered in, a dump would
be great.

The answer was like "uhm, we don't have it ourselves, but it would be
great if you could share your knowledge with us once you read it out"
and "don't worry, we have plenty of replacement CPU boards for $80 a
piece".

I'm still unsure whether I find this hilarious or frightening.
