The DISER Lilith is a custom built workstation computer based on the AMD 2901 bit-slice processor, created by a group led by Niklaus Wirth at ETH Zürich. 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."
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, selling it under the company name DISER (for Data Image Sound Processor and Emitter Receiver System). 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.
