[QuadList] This has to be a record

[Gary Adams]

I am not the expert on this list but I think NYC had older equipment.
Dennis' pictures are pretty good.  At the same time I was spending some time
with a woman that worked in the Burbank TCR room.  All of the channel
control was run by General Automation computers which pretty much had lots
of switching transistors and relays.  There was some serial control of
things as well.  I'll try to dig out my photos on this.  At that time, the
channels in New York were for multiple feeds not counting the time zone
delays.  Feeds such as local channel and multiple sports on the weekends.
In fact the time zone delays at that particular time were driven by a system
built by the company I was working for.  A computer system recording one
feed and delaying for multiple hours.  It was mostly automatic.  Controlling
Panasonic cassette machines.  You are probably describing what happened just
prior to the time frame I am speaking.

Unrelated, in the 80s, I had a contractor job at NBC in New York, to
document the addition of a few more channels in Switching Central.  Looking
over Dennis' photos brought back memories.  In fact, I opened the door to
the announce booth and caught Don Pardo on the phone with his broker no
doubt.  I have in my garage, many drawings of the system at that time period
to include the exact wiring of the GA computers and the complete equipment
makup of a single channel and path. It's pretty interesting.   If anyone is
interested in it, it doesn't need to sit here.  Mostly blueprints which
would  be somewhat faded but not completely.  I knew many people previously
having worked for RCA prior but I wasn't a normal fixture there.

Gary,

Was switching central in NYC at that time similar to Burbank, where the
whole system was hand built, with relay switching in many, many racks,
TP-90, TP-5 (Time Preset), etc.? This drove all of the record VTR's out West
for zone delay recording and such (with someone watching over it). Gray
panels with rear lit huge numbers?
