The family came in four flavors: ''5781'', ''57129'', ''5799'', ''75140''. The ''5781'' was a multi-chip solution allowing more advanced calculators to be designed. The ''57129'' is a larger version of the ''5781''. The ''5799'' was a single chip equivalent of to the ''5781''/''5782'' system. The ''75140'' contained everything including calculator keyboard input and display driver.

The Controller Oriented Processor System I or COPS I (originally just COPS) is a family of 4-bit microcontrollers developed by National Semiconductor. COPS, as it was originally called, was released to the market in 1976. It was manufactured in PMOS technology. A year later, National introduced the COPS II, an NMOS (and later CMOS) versions of those chips.

The MM5781+MM5782 solution allowed for more complex designs whereas the MM5799 served as a single-chip solution. The MM57140 was an even more advanced chip incorporating the keyboard input and display driver.
