<DIV>The CMX 600 was a unique system. I saw only one of them, and it was
at One Pass Video in San Francisco. The place burned down when a fire
started on the wharf next to the building. The 600 was a disc based system
that used black and white images to build a show and edit list. Then it
was taken to an on line room. The system was so expensive. It was
out of reach for almost everyone.</DIV>

<DIV>The first CMX that I had experience with was a 340. It also had the
DEC PDP as the CPU. It also had core memory that allowed you not to have
to boot the system from paper tape every time. In fact I still have a
paper tape in the basement. The amazing thing was that they had to do
everything in 64 K of memory. The display was a terminal built by Ann
Arbor Terminals here in Michigan. We had the high speed tape reader and
the LA-36 printer on each system. The system was OK but there were always
bugs in it. Many we did not see in every day use but they would drive us
crazy at times. </DIV>

<DIV>Some of the design considerations for video and audio were not that
great. The 2 x 1 preview switcher did not have any headroom and sounded
terrible. it was designed with the audio levels of off line machines in
mind. The interfaces were not always for the correct model. The
AVR-2 interface was based upon an early machine. Thus modifications and
updates were not taken into account. </DIV>
<DIV> </DIV>
<DIV>Stupid operational things. Like if the machine was playing and you
threw the switch on the I squared, it would stop the machine. Hit the
wrong I squared and oops tape on air stops.</DIV>
