Actually, in the category of data that I have easy, web-based access to, I'm finding that I'm having the best luck with patent searches.  As I find interesting ones, I'll post the links.  I plan to put them all at scribd.com to provide one-stop (free) shopping.  To start, here's the link to the 207 page ENIAC patent:

If anyone knows of patents likely to have good tube or relay logic circuit descriptions within them, please give me the patent numbers and I'll post the patents as PDFs on scribd.
