[sdiy] TR-707 Mods and trigger outputs - advice wanted

[steve jones]

Hi,
I am looking for any info / web sites for modifying the TR707 drum
machine - is it possible to get more 5v triggers out from this
machine? (it has 1 as standard).

Alternatively, is there a simple circuit which could plug into an
audio out socket, to produce a trigger? ie drum sound to 5v trigger
adapter. My aim is to use the 707 sequencer to play some home built
drum synths :

I am also interested in modifying the TR707 internal sounds if that is
possible.

Any tips most welcome.
Cheers
