[QuadList] Picture of the day (link to)---and who's in it?

[Bill Carpenter]

 Hi Park,

I believe you are right, I never was involved Zeus other than a user. 
The big value related to not messing with the head was increase head life when 
you did not change position of the guide. A coating built up on the heads which 
created a protection layer. 


We would leave the head in the record position at all times unless I was 
demonstrating the capability of the TBC to remove guide related errors.

I also did a demo where I would show recorded color bars and then due multiple 
insert edits of other style bars to show the edit quality.

I made a mistake and after showing the guide error handling capability, where 
both height and penetration were cranked to extremes. Then I did the insert edit 
demo, and never switched the head back to record position. 


I made about 10  edits in a row, and went to playback and the Director of 
Engineering ( Glen Lehman) for the group stopped me, and and took over the demo. 


He got on the intercom, got everybody involved with tape into the demo area, and 
explained that I had made the worst case edits that were possible, and showed 
demod out, and then switched to the TBC out. Everybody clapped, and then I 
figured out what I had done, which was very bad, but turned out great!
He  explained what I had done accidently, later in the bar, with bar napkin 
notes. Since, I was never a quad operator, I was keeping the Demo moving, and 
made a true "Worst Case" tape and did not realize what I had done.
Needless to say, this mistake was included in all future demo's.

Bye for now, Bill Carpenter

I found the same thing with the NECTBC on the Merlin retrofit. No matter how off 
the guide are, the output is perfect. I have to look at demod to see how the 
guides are set.

The NECTBC is 10 bit. I don't think any Ampex Quad ever had a 10 bit TBC. Wasn't 
the first Ampex 10 bit TBC the Zeus???


Best,
Park

And it also had the best video head life (no guide servo) since you could leave 
the guide in one position and let the TBC and the AutoChroma do their jobs
