Description
When performing numerical calculations using the FACOM 100, the user would create an instruction tape and numerical value tape using the paper tape puncher to the right of the operating console (see the photo "Equipment Comprising the FACOM 100 System"), and those tapes were then read, respectively, by the instruction tape reader and numerical tape reader. Calculation was done by following the instructions given on the instruction tape, and reading data from the numerical value tape. A printer and tape punch were used for output.
