Looking forward to seeing your collection of Rainbow disks ... looks like you have a fantastic amount of originals.
I bought what I think was a Rainbow User Group's old lending library years ago (though maybe it was just a packrat who liked to backup things) when I lived in Palo Alto years ago and then stuck them in a box and forgot about them for a long time... But it turns out that there's some cool things, and a lot that's duplicated on one of the online archives.... sorting through it all is a bit pita... (though some of that I bring on myself, since I'm also a bit of a packrat, I've had my Rainbow 100B since 1984 and still have many of the original receipts from purchasing it, turbo pascal, etc)
