60497 Hollerith Punched Card Reader

Description of Photograph

Photograph of the British Tabulating Machines (BTM) Hollerith Punched Card Reader, part of the LEO I installation at Cadby Hall (the same machine was later used on LEO II). Evidently the image was taken at an early stage, as the card machines were finally situated in front of the power supply units in what became the peripherals area.

According to Peter Bird's caption on the reverse of the print, the Card Reader was capable of processing 200 cards per minute.

This image appears in the interactive plan for our Virtual LEO I installation, p33.

Provenance
Collected by Peter Bird as part of his research for his book LEO - The First Business Computer (1994).
