Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

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.

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