I've put up a few scans I've made here:

I'll add more as I acquire them. I'm more interested in historic items I can make my own scans of, rather than just stealing documents from other sites around the web, even if it would be convenient to have them all in one place. But if you have something of yours you'd like to have me post there, I'd be happy to. Including lending me stuff to scan and send back to you.
For instance, is there an "owner" of the gears program? I managed to find a copy of gears.zip via the Wayback machine, but it's not really mine to re-post I think.
Note that I scanned the copy of the instructions that came with my camera, which is just a copy of the originals that Jim Lipari made way back when, but I kept the back cover with his info intact, as an homage to him, and I don't believe his heirs are currently selling copies of it, so I feel it's OK to post the scan. I'll certainly be on the lookout for originals of my own to scan in the future also.
