Technician Operating Early Computer System with Magnetic Tape, San Francisco State College, November 1971

Equipment Identified:

  Computer Console (bottom center)

• This is the operator control console, used to input commands and monitor system status.
• The console has toggle switches for manual data/program entry (likely hexadecimal or binary), and indicator lights for address, data, and status bits.
• The keyboard below is for typing commands.

  Tape Drives (middle & top center)

• The two spools with white reels are magnetic tape drives, used for loading software, backing up data, or storing large datasets.
• These tape reels hold data on magnetic strips and are often used to transfer programs or log computational results.

 Paper Tapes & Reader (left)

• Rolled strips on the left are paper tape rolls, used for input/output of program instructions or data.
• The vertical slot above them may be a paper tape reader or punch, a peripheral for feeding this data into the system.

 Disk Drive Cabinets (right)

• The units on the right (with dark front panels) are likely early hard disk drives or drum memory storage, which stored large volumes of data permanently.
