I'm a freak for drum machines. I love the Roland tr-606, vintage 1986 analog coolness. But i'm poor and I can't afford a tr-808 or a Jomox drum machine, so in the spirit of melting holes in things, here's pic's of my modifications. All of these can be easily found on the internet, and with a little patience and a very small investment in parts you can do these too, they're dead easy. My only reccomendation is to use shielded multiwire cabling to keep things neat inside your machine. There's not much room in there.
