[1] Their systems predated the personal computer era of inexpensive graphics displays, and were typically used as peripheral devices, connected to a mainframe or minicomputer.

Chromatics pursued the higher performance end of the graphics marketplace, including such applications as flight simulation and air traffic control.

Programs running on that "host" machine would generate commands in Chromatics' proprietary graphics language, and transmit them to the CG.

The CT series was a lower-cost product for Chromatics, designed around the recently introduced NEC μPD7220 graphics display controller chip.

The CT4100 model had the same form factor as other CT series machines, but was the only Chromatics system with character-cell (not pixel-addressable) graphics.

It was intended to directly compete in the process control display terminal market, against Hughey's previous company, Intelligent Systems.

Due to the limited graphics flexibility available in this type of display, the CT4100 also included a downloadable character set allowing user-definable glyphs.

[7] Both the CG and CGC 7900 systems had large keyboards with dedicated function keys to select colors, choose graphics modes, and perform similar operations.
