Modcomp, Inc., originally Modular Computer Systems, was a small minicomputer vendor that specialized in real-time applications.

Through the 1980s, Modcomp lost market share as more powerful micro-computers became popular, and Digital Equipment Corporation's VAX and Alpha systems continued to grow.

The company successfully survives today as a systems integrator operating as CSPi Technology Solutions headquartered in Deerfield Beach, Florida.

[1][self-published source][2] The core architecture of the 16-bit machines included blocks of uncommitted opcodes and provisions for physical modularity that hint at the reasoning behind the company name.

In addition to a very capable Macro-Assembler, the Fortran system also was designed to take advantage of the multiple registers to temporarily hold the values of variables and indexes.

The compiler also had optimization which reduced the number of operations required to process math expression most often found in indexing into arrays.

[4] Many of Modcomp's early sales were for tracking and data collection from NASA space probes, and in the 1980s they provided a network of 250 Modcomp II systems to control the Space Shuttle launch complex at Cape Canaveral as well as SET at SAIL at JSC until T-30, at which point control was handed over to a single IBM mainframe.

[1] In the 1990s Modcomp developed a product in the UK called ViewMax, which was used to connect web-based "front-ends" to legacy systems.
