English: A picture of the Pegasus computer system, originally installed in University College London's basement, showing the signature Ferranti clock on the front panel, the four lacquered cabinet doors (most Pegasus machines had only three cabinets, but this particular unit had expansion space for a tape unit interface, which was never installed). In the foreground to the left of the machine are two 5-hole punched tape readers, and to the right a tape punch, which feeds a line printer. In the background to the left behind the machine sits its power supply cabinet. The cabinet was built by Rolls Royce hence the car door handles.
