The DISER Lilith is a custom built workstation computer based on the Advanced Micro Devices (AMD) 2901 bit slicing processor, created by a group led by Niklaus Wirth at ETH Zurich. The project began in 1977, and by 1984 several hundred workstations were in use. It has a high resolution full page portrait oriented cathode-ray tube display, a mouse, a laser printer interface, and a computer networking interface. Its software is written fully in Modula-2 and includes a relational database program named Lidas.
The Lilith processor architecture is a stack machine. 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."
