I was out and about yesterday and ran across a couple of items:
Introduction to Computer Programming for the Social Sciences (1973)
It seems a significant portion of the programs included were developed
on a Raytheon 706, even though the programs generally are for and IBM 360
IBM System/370 Principles of Operation (1981)
Not quite pristine, but it looks like it spent most of its life sitting
around somehwere. The spine mastic is broken, but it doesn't look like
it was ever put into a binder.
