<DIV>I've recently received a great deal of information on the CMX 300 & 400
systems. Included is a 55 page training manual in 11"x17" format that
was developed by NBC Burbank. I've included a scan below of the
introductory page. I never worked on these systems, but I did have many
years of experience with DEC PDP-11's in other applications, so the opportunity
to learn more about how two of my favorite technologies came together has been a
real treat. My first experience with the PDP-11 in an editing environment
was the Ampex ACE, and that was a decade after the CMX systems were
developed.</DIV>
<DIV> </DIV>
<DIV>The comparison of this technology to todays' world of non-linear
editing is such a striking contrast that it's probably inconceivable to
many people in the industry today. Perhaps the idea of having an edit
system composed of tape machines is not too far removed from most of our
memories, but concern for what bits in which register are controlling which
machine function disappeared a long time ago. An editing system
with diagnostic routines to monitor specific bits on a data bus just isn't
standard fare anymore! </DIV>
<DIV> </DIV>
<DIV>I don't know how rare or how common the existence of these documents may
be. Have any of these systems been preserved? I'd like to find the
most effective way to ensure that this information is not lost. Perhaps
the folks at Woonsocket would be a good repository? Ideas, suggestions or
comments?</DIV>
