content: The Burroughs Adding Machine Company, long a manufacturer of full-keyboard adding machines, faced stiff competition from less expensive ten-key adding machines. In response, in 1954 they introduced their own versions of the machine, based on the British Summit. This is a prototype, designed for British currency.
label: Description
content: The manually operated printing machine accepts nine-digit entries and prints nine-digit totals. The gray metal machine has 11 white plastic keys in a block, numbered from 1 to 11. There also is a white zero bar and a white key labeled with a pound sterling symbol. There are 4 brown function keys right of the digit keys that are labeled ST, T, -, and R. The place indicator is in back of the keyboard and the printing mechanism, with 2-1/4” carriage, behind this. The ribbon is black. A lid lifts off the top for access to the ribbon and printing mechanism. The top part of a wheel is exposed through the case to allow one to advance the paper tape. A serrated edge assists in tearing off the paper tape.
