No quite so... as a result of the first new development for Quad  
videotape in decades!

As we announced at the Quad/Editor/Telecine lunch at NAB...
There's a new board set that will take care of making an AVR-2 capable  
of running high band c/m and Low Band color and monochrome with just a  
few switch flips or turns.

This makes it possible to standardize on the AVR-2 as a machine of  
choice for these tape formats.

The board is an outgrowth of Ken Zin's execution for his own AVR-2. He  
and long-time colleague Al Sturm have collaborated on the design. Al  
is handling the manufacturing details and I'm marketing it.

The set replaces the demod card, and modifies the EQ/Switcher card to  
work with the new demod.  It can be set up to work with NTSC and PAL.

Please contact me off-list at ted at flashscan8.us for further info.

Beyond Low Band Color...
There's also the possibility of a slightly different board set to  
allow AVR-2 transfer of RCA Labs color and RCA color, those wonderful  
pre-low band heterodyne formats used on the WRC-TV dedication  
(Eisenhower tape), the "Evening with Fred Astaire" recordings and  
other shows done at NBC or on early color RCA machines.

That's taken mods to 10 or so AVR-1 boards to accomplish. QuadList  
member Ed Reitan did it in 1987/88 to enable recovery of the  
Eisenhower and Astaire tapes (among others) with Don Kent operating  
the KTLA machine. That's now in CBS-TVC (with the boards, I'd think.)

QuadList member David Crosthwait did it for one of his AVR-1's a  
couple of years ago and presented a short talk w/powerpoint at the  
AMIA 'Reel Thing' in St. Louis.  It took some late night soldering- 
iron sessions and a lot of reference to the RCA TRT-1C manuals he has  
to reverse engineer the process and develop his set of mods.
