Old Drum Machine Preset Patterns?

So I have seen many old drum machine sounds, samples, etc. But I have never seen or found the canned patterns that came with these machines. Do they exist somewhere in midi? Even sound clips of the patterns? I realize not all machines came with present patterns, but some did.

I used to have a SR16(not real old, I know) and I was thinking about a particular cheesy pattern I wanted to use for something I was working on which got me thinking and looking.

Just curious…

SynthMania is the closest thing I’ve seen to what you’re looking for.

They have a page on the SR-16 with MP3s of all the preset patterns: http://www.synthmania.com/sr-16.htm
