Introduced in August 1989.
The TC2000 was the first large-scale implementation of a RISC architecture in the late eighties. It was targeted towards real-time simulation, industrial process control, decision support, on-line database management, and project planning and control. It was a scalable shared-memory multi-processor architecture The TC2000 allowed expansion of the base system from eight to 128 CPUs, with each CPU sitting on a designated processor board. The architectural limit was 512 CPUs, though there weren't any system delivered in that size.
The price for a base model was in 1989 was $350,000; BBN stopped selling these systems in 1991.
Maximum theoretical system capabilities were, for 504 processors:
