My advice is don't do it. I remember many years ago, I sold a
perfectly-working TR-606 in near mint condition, with the carrying
case, manual, original Roland batteries, etc. to some kid on AH. A
week later he posted how he completely butchered the thing trying to
mod it.
Imho, the sounds of the TR-606 aren't all that great, and its
sequencer isn't as good as the 707, 808, or 909. That being said, it
already has two trigger outs.
If you still want to add individual outputs, then the way to do it is
to measure how much space you have, then look up the dimensions for
whatever jacks are available. Mouser usually has links to the pdf
files from the manufacturer.
Still, I think you would be better off getting an 808, or buying or
building some analogue drum modules. Used "drum brains" from Tama,
Simmons, etc. (which can be triggered from the TR-606 HT/LT outputs)
are fairly inexpensive.
