1974 MA: John Robinson in the Computer Department
This is the computer department at C&K Components in 1974.
The IBM System/3 (introduced 1969 discontinued 1985) was a low-end business computer aimed at new customers and organizations that still used IBM 1400 series computers or unit record equipment. It was the first member of what IBM refers to as their "mid range" line.
It featured a new punch card format that was smaller and stored 96 characters. Instead of the rectangular punches in the classic IBM card, the new cards had tiny (1 mm), circular holes much like paper tape.
For mass storage, the System/3 used a single-platter disk, roughly the size of a large pizza; initially each platter held 2.5 MB of data. Standard configuration for storage was one or two fixed disks, each in a separate pull-out drawer, which typically held the operating system and user-developed programs. Additionally, each fixed disc could have a removable cartridge disk attached; these typically contained the data-files associated with various applications, for example Payroll, and users frequently had a number of them. Thus the low-end systems could support a maximum of 10 MB of online storage (two fixed, 2 removable), although in practice this was very expensive and not always common.
System printing was typically via line printers or bi-directional dot matrix printers. A modified selectric typewriter was often used as a console.
The System/3 came standard with a RPG II compiler, and used a version of Job Control Language called OCL.
