Lilith (computer)

The vertical screen, keyboard and mouse of the Diser Lilith
Vertical tower central unit.

Lilith is the name of a custom built workstation using the AMD 2901 bit-slice processor by the group of Niklaus Wirth at ETH Zürich.[1][2] The project started in 1977 and by 1984 several hundred workstations were in use. It had a high resolution full page display, a mouse, a laser printer interface, and a network interface. Its software was written completely in Modula-2 and included a relational database program called Lidas.

Citing from Sven Erik Knudsen's contribution to "The Art of Simplicity": "Lilith's clock speed was around 7 MHz and enabled Lilith to execute between 1 and 2 million instructions (called M-code) per second. (...) Initially, the main memory was planned to have 65,536 16-bit words memory, but soon after its first version, it was enlarged to twice that capacity. For regular Modula-2 programs, however, only the initial 65,536 words were usable for storage of variables."[3]

History

The development of Lilith was influenced by the Xerox Alto from the Xerox PARC (1973) where Niklaus Wirth spent a sabbatical from 1976 to 1977. Unable to bring back one of the Alto systems to Europe, Wirth decided to build a new system from scratch between 1978 and 1980.[4] In 1985 he had a second sabbatical leave to PARC, which led to the design of the Oberon System. Ceres, the follow-up to Lilith, was also released in 1985.

The mouse of the Lilith was custom-designed, and later used with the Smaky computers. It would go on to inspire the first mice produced by Logitech.
