Two items are umm substantially priced, my IBM 7090
reference
manuals. It's possibly, even likely, insane, but hey, it's only
bits (and cash).
I re-checked the manuals, these really are for 7090, not 709x,
so they're really old. LASL (Los Alamos Scientific Lab) was an
'early adopter' for everything. The 7090 is pre-STRETCH, which
was built partially for LASL.
