Antwort: [sdiy] AN6912 IC in TR-808?

[Christian.Bergmiller at daimlerchrysler.com]

Hello!

the an6912 is a quad comparator (those with open collector output)
It can be replaced with an lm339 (its even pin compatible when i remenber right)

while i was building the handclap section of the 808 some time ago i noticed an 
error in the
schematics from roland. 
C140 is noticed as 2n7
handclap started working when i changed it to 27n...

The SnareDrum section had some "Portion Changed" notices
with this changed values the snare drum sounds not the same way it does in some 
mp3 samples
(taken from an original 808) i found on the net
anybody out there who did research on this yet ?

bye
Christian
