...finally...i managed to put the Kiwi JX-3P upgrade into my JX-3P...
 ...i had some minor difficulties though, as my kit did not match the
 current description/manual on the kiwi-website...
 ...especially the chorus-upgrade (v. 1.0) looks very different from
 what is pictured in the current manual...guessing i just placed the
 cables - four of them - into the corresponding holes of where i had
 removed IC2, respectively pins 1, 2, 4 and 5...right?...
 ...after a reboot using the 'write-write' combo i am now curious what
 is waiting for me in my new machine - it does make sounds already, so
 perhaps i was not completely wrong :o) ...
