Well
 
This has to therefore be a CMC DOC module.  The thought was that  Merlin 
might of done something, but after further thought, I do not  remember any 
products from them like this.

You definitely got some of it right, certainly the best  answer so far, but 
not 100%, so I'll let this play out a bit longer before  confirming any 
specifics.

You deserve an "at a boy" for getting a good one.  First this is a  board 
with 24 pins so it fits the signal system of the VR-1200 or  VR-2000.  Next 
the previous respondents noted the delay line.  So  the only conclusion that 
I can come up with is that this is a one line delay  module for the VR-1200 
or VR-2000.
 
Next is the fact that this is not the Ampex color for a circuit  board.  
Therefor it was made by another manufacture.  Also the  IC's on it suggests 
that it may be after market.  Date codes indicate  that at least one of the 
IC's was manufactured in 1978.  So how about  CMC or Merlin?
