[QuadList] IVC 900 series 1" (was 1970 3M Industrial Tape Sales Sheet coming soon)

[Ted Langdell]

The 900 series seems to have been attractive for a lot of small market stations.  

From Marysville in the middle of the mid-Sacramento Valley, I'd occasionally be able to see KFTY, 50, Santa Rosa from its Mt. St. Helena TX site if I cranked the Yagi due west. Didn't realize you'd worked there, Mike. :)

Around that time, I recall seeing at least one, maybe two 900 series machines at KRCR-TV, 7R, Redding, along with IVC cameras. Wish now I had shot pictures. I think they were in overbridge consoles.  Think I was told only one had a TBC.

I DID shoot pix at WHIZ-TV, 16, Zanesville, OH in 2006 or 7... (hard drive's they're on not immediately at hand or I'd post a pic) and those helped them find a new home in Los Angeles.  Two 960's and a 900.

Looks like IVC Blue (900 series) next to the AVR-1's Ampex Gray.  

In the back corner, it looks like the microscope eyepiece of a Smith Splicer sticking out from between the racks and just to the right of that, a second generation Ampex Quad peeking out from behind a film island camera.

Don Norwood and Chris Hill ID'd the corner Quad as a VR-1100 and spotted a number of other things.  That was a good thread.

When comparing the "formats", you have to be careful to compare both the format itself and the particular machine model being used.
