Maybe you know about the early (first?) 6502-based computer, the KIM-1 from 1976. I recently built a replica (the PAL-1) and wanted to flip through some of the original documentation. Fortunately archive.org has quite a bit of early KIM-1 texts.
I pulled down the KIM-1 Users Manual as a PDF but after printing it out and comb-binding it, I decided I would rather have a more polished softbound version so I created a book project on Lulu.
The PDF was suprisingly clean, only the cover was a let-down. So I used my favorite vector-based drawing app, Affinity Designer, and recreated the front and back covers.
Shipping is such a factor in the cost that I went ahead and had Lulu print up eight extras. I went ahead and set up a Tindie site to sell the extra copies.
