Mainframe worker accidentally canceled a week-long inventory print job

Mainframe worker accidentally canceled a week-long inventory print job

A worker at Sperry Univac’s UK office made a costly mistake while operating an old mainframe computer.

The system used punch cards and printed its results instead of displaying them on a monitor.

One weekly inventory job took five or six days, including printing, and three managers had traveled from the United States to watch it.

When a separate job produced too many pages, the worker canceled its printing after checking with the programmer.

But the printer that stopped was the one handling the inventory results, and the output was lost.

The inventory job could not be completed successfully until it was run again the following week.

The managers were unable to proceed until then, although the worker said colleagues were sympathetic and did not blame him.
