Engineering:Clary DE-60
The Clary DE-60 was an early transistorized digital computer made by Clary Corporation.[1] It was a compact (desk-sized) general-purpose computer intended for both scientific and business applications. It operated on 18-digit binary-coded decimal words used fixed-point arithmetic. Main memory was a 32-word magnetic drum memory. Input and output devices included a console keyboard, printer, paper tape and punched card system. For programming, the system used sequential instructions from the keyboard and plug-boards.[2] [3] Custom modules for trigonometric and other functions could be installed.
The system was introduced in 1959.[4] By 1961, about 18 systems were operating or on order. Clary Corporation was founded by Hugh L. Clary in 1939. Today the company manufactures products such as uninterruptible power supply systems.[5]
