I have access to a big commercial copy / printer. I have manuals in digital
copy some are OK scans , some are high quality. Ones I do print get printed
on 8x10 sheets double sided. Not ideal for schematics but its free...you
just do a lot of page flipping when tracing circuits.

I've successfully used them to resurrect a R-392 and R-390!
