Lilith Workstation

The Lilith was one of the first computer workstations worldwide with a high-resolution graphical display and a mouse. The first prototype was developed by Niklaus Wirth and his group between 1978 and 1980 with Richard Ohran as the hardware specialist. Lilith was strongly influenced by the Alto computer developed at Xerox' Palo Alto Research Lab in California, with which Niklaus Wirth had been working during his sabbatical in 1976/77. He was impressed by the system, but unfortunately the Alto computers were not for sale. On his departure day, though, he was presented with a computer mouse he liked so much as an input device.

The whole system software of the Lilith was written in Modula-2, a structured programming language which Wirth has developed at the same time. The programs were compiled into low-level M-Code instructions which could be executed by the hardware. The user interface was designed with windows, icons and pop-up menus. Compared with the character based systems available at that time, these were revolutionary metaphors in the interaction with a computer.

The main goal in the construction of the Lilith Workstation was its application in the educative field. Additionally, it was also used for administrative work at the institute. As a matter of fact, the Lilith soon also became a basis for various other research projects. An attempt to commercialise the Lilith computer was undertaken in 1982 but was given up after a short time, eventhough the Lilith already at that time had all the characteristics which would distinguish the much more successful Macintosh, presented in 1985.
The idea of naming the computer "Lilith" Wirth was given by a friend who told him about a men seducing daemon bearing that name. Members of Wirth's group would be working at nighttime and over the weekend for the Lilith project and were literally seduced.

The Lilith proved itself during the 1980s in the daily business as well as for educational application. However, the growing requirements did not simply leave it unaffected, and thus the workstation development at the institute was continued over the years. The research interests were not in processor architecture anymore, but rather in the integration of modern hardware technology. Together with Hans Eberle and later with Beat Heeb, Wirth began developing the Ceres series in 1984, presenting the first genuine 32-Bit computer a couple of years later. In 1990, the second revision of the system was finished and 100 Ceres-3 machines were produced in Switzerland which were used for the equipment of computer labs. Parallel to the development of the Ceres computers, the change from Modula-2 to Oberon as the language used in programming courses and from Medos to Oberon as the operating system was effected.
