punch card 1974 EX

An old-fashioned computer 80-column punch card with a line of FORTRAN on it, as written by the photographer at the City College of San Francisco. (CCSF) Taken in 1974 (slide processed in April) by a Honeywell Pentax SP1000 with a SMC Takumar 55mm ƒ2 lens on Kodak Ektachrome-X., process E-4. Mounted slide scanned into computer by an HP G4010.


Vignetting by the slide mount. This is taken at 1.5 feet, the closest that that lens will focus...


At the time taken, this was still how you entered data into a (mainframe) computer...
