Its products powered a variety of applications, including those for aerospace simulation, data acquisition and control, and signal processing.

The origins of Harris Computer Systems began in 1967 in Fort Lauderdale, Florida, when Datacraft Corporation was founded.

[2] The Slash 1 made cost-effective use of hardware for floating-point operations and quickly became popular as alternatives to computers from Systems Engineering Laboratories.

[2] The Harris Computer Systems Division then came out with the H-Series product line, which featured virtual memory as a key aspect.

[3] H-series products were generally good at maintaining binary compatibility, meaning old application executables could still run on newer models.

[3] In addition, as a company involved in defense-related contracts, Harris Computer Systems Division came out with a line of Ada programming language compiler products.

[4][5] In 1984, Harris Computer made its first forays into having VOS co-exist alongside the Unix operating system.

[8] The Harris Computer Systems Division also made a network firewall product, that they sold to their governmental agency customers.

[12] The company's main product was (continued to be) the Night Hawk computer system, which featured high performance, multi-processing, and real-time capabilities.

In addition to compilers, the company put out APSE-related runtime environments with symbolic debugging and tracing capabilities.

[17] During the mid-1990s, Harris Computer Systems was also involved in the process for revising the Ada Semantic Interface Specification.

[20] While in theory the best components of each company would be the ones moving forward,[20] in practice it was the PowerPC-based Night Hawk business that mostly continued, while Concurrent's own product, based on a different processor, was de-emphasized.
