Teletype Model ASR-33

Released in 1971, the CMX-200 was the auto-assembly half of the CMX-600.
It wasn't intended for interactive editing. The CMX-200 had a minimum of
commands, and was controlled by an ASR-33 Teletype. The Teletype was also
used to load the edit lists produced by the CMX-600.

Often after a program was conformed using the CMX-200, fixes, or minor
changes might be required. The CMX-200 was of limited use in making these
changes.
So in 1972, the 300 was born as CMX's first online editor.
The CMX-300 was "THE" editor of its day.
It handled edit lists,
controlled four VTR's (generally 2" Quad VTR's) and included a
simple audio mixer and video switcher (with wipes and keys).
Many of the feature of today's linear editors were first developed on the
CMX-300.

The CMX-400 was designed for offline use. It was the basic CMX-300
hardware and software, but was used with IVC 870 1" helical scan VTR's.

Released in 1976, the 340 continued the CMX tradition of linear editors, the major
innovation in the CMX-340 was the introduction of the Intelligent Interfaces
or I2 (pronounced eye-square) concept.
This allowed the user the freedom to use any
combination of VTR's in the edit session.

The I2 was an elegant solution to a major problem. Most of the available
VTR's required parallel control, and external time code readers. The same
was true for the video switcher and audio mixers.
|
To deal with these hardware differences, each I2 was designed to control
a specific VTR or switcher.
But, the communications with the CMX-340 executive was standardized. Thus, to
the edit system, all machines looked and acted the same.
A brilliant solution to a knotty problem.
