Was the cost of $110.00 the cost for the software or the cost of the manual?
I thought the software was much more.

a CDC 6600 or 7600, when those became available - Those were the big iron for
numerical computation back then (60 bit single precision). That's what I was
using from around 1974 to 1980 at various places. But yes, keypunch,
lineprinter, maybe a RJE terminals.https://computing.llnl.gov/history shows
them getting a 7600 in 69, in addition to the 7600 they got in '64 (which
replaced the IBM 7030) (it was Serial number 1)NEC2.f (from 1980)C PROGRAM
