[sdiy] tr909 schematics -> sequencer part

[Rude 66]

does anyone have or know the online location of the tr909 schematics? i just
found out mine didn't survive the last gig we did..
all the sounds are there, but the sequencer is mad! some buttons don't work,
etc. it's behaving like there;s a loose contact somewhere in the sequencer
section

i need to know only the sequencer part.. the voices all seem to be ok. but
all i can find online are parts of the schematics for the different voices..

my thanks forever! ;-)
