System 3125 tablet computer

Made by NCR Corporation, 1991.

The NCR System 3125 is a sophisticated tablet, or pen-based portable computer. That is it does not use a keyboard or mouse for the input and retrieval of data. All the computer’s programs are accessed by the use of a ‘pen’ - a stylus that is designed to interact with the surface of the screen and either input text which is read by the computer and interpreted as commands, or activate virtual buttons on the screen to open, access, save, edit and close programs.

Tablet computer with an LCD screen and a moulded beige-coloured plastic surround. The unit sits flat with the screen facing upwards for use and can be hand-held in the same position. The power button is situated on the top right corner of the unit, with cable ports on the left hand side. The tablet is accompanied by a stylus, connector adaptor, transformer, electrical cord and protective case.


The tablet computer was designed and manufactured by the NCR Corporation, Germany, 1991.

The company began in 1884 as the National Cash Register Company, a cash register manufacturer in Dayton, Ohio, U.S.A. The company was successful, as retailers quickly realised that profits could be accurately recorded, and cash theft by staff greatly reduced once they introduced cash registers to their businesses. NCR neared bankruptcy in the early 1930s due to the Great Depression, but managed to stay afloat, and in 1952 the company secured a defence contract for designing bombing navigation computers - and this started NCR's computer division. NCR also entered the commercial computer market, but the company had much more success in the manufacturing and marketing of automated teller machines (ATMs). This is still a major component of NCR's core business. The NCR System 3125 tablet computer was brought onto the market in 1991. It was a high-end notepad computer, designed for the white-collar market, combining the convenience of a highly portable system, with the power of a small PC to manipulate sophisticated data. It used the Intel's i386 SL microprocessor.
