Raspberry Pi Zero vs Elliott 405

Twitter users @SadHappyAmazing and @HistoricalPics posted yesterday two photographs (copy) showing the Raspberry Pi Zero juxtaposed in front of the Norwich City Council Treasurer's Department building, where the delivery of the Elliott 405 computer was photographed in 1957. Here is how the two computers compare.
