ISRA VISION PARSYTEC AG is a company of ISRA VISION AG and was founded in 1985 as Parsytec (PARallel SYstem TEChnology) in Aachen, Germany. Parsytec has become known in the late 1980s and early 1990s as a manufacturer of transputer-based parallel systems. Products ranged from a single transputer plug-in board for the IBM PC up to large massively-parallel systems with thousands of transputers (or processors, respectively) such as the Parsytec GC. Some sources call the latter ultracomputer sized, scalable multicomputers (smC).
