I work IT for a living. There is a method of comparison for Supercomputers they are rated using by teraFLOPS on the MP-Linpack. A teraFLOP is one trillion floating point operations per second.
To give an example, the Sandia Asci Red supercomputer, built in 1996 was rated a 1.5 teraFLOPS. Today, that machine can be outdone by a Sony Playstation.
Judging by the photo with the array of tape drives, etc. The sysop is sitting at a desk with keyboards and monitors, those were later developments. Very early machines had only card readers and printers. OCAMA was Oklahoma City Air Materiel Area. This was a data center for the Air Force that was an offshoot of the Rand Corp. Circa 1965. Your watch has more computing power.
