[QuadList] 1970 3M Industrial Tape Sales Sheet coming soon

[mike at bolandcom.com]

The IVC 900 (& 960 editing machine) were highband (7.06-10 MHz) 
tension-servoed
machines that would accomodate large reels for 1.5 hour programs.  
Used with the
DOC and "wide" window (40 µs?) 4102 analog TBC, the machine gave 
better playback

performance than many contemporary quad recordings.  (Many, maybe most, quads
at the time did not have Velcomp or Autochroma to fix guide-position 
errors caused
during recording.)

I had the pleasure (!) of working with the first two On-Air 900s at 
KFTY in Santa Rosa
in 1972-73, one on in the truck, and one in the studio.  Not much 
publicity given to
that 1st roll-out status, as it was more of a beta site than 
anything!  At least IVC was
less than 2 hours away!

  Ted:

I didn't see anyone else answer your question, so......  IVC 900 
series is the answer. 
   
  And this fits into the discussion about IVC vs Ampex.  The 900 
series was more advanced than the 800 & 700 series, and was more on a 
level with the VPR-7900 series.  When comparing the "formats", you 
have to be careful to compare both the format itself and the particular 
machine model being used.

  Trivia question:  Can anyone tell what machine a 12.5" reel of 
Scotch 361-1-7500-VRB was used on?

        The tape was sold two reels per carton at $213 per reel in 
1970. An empty reel was $17. 

  Clue:  The same machine would play reels of 361-1-1075-R139B 
and 361-1-2150-R139B if they were recorded on other machines that used 
the same format. 

  These smaller reels were $34.55 and $45.30 per reel in cartons of five.
