[QuadList] Ampex RA-4000

[Bill Carpenter]

Hi Chris,

In the days that SMPTE time code was being finalized, the code was to be 72 or 
maybe 75?

Stan Busby of Ampex reviewed the documentation, some which was offered by one of 
the early time code equipment designers, 

which may have been ECCO.
He created a very strong counter proposal to move it up to 80 bits. 

Ampex and others were working on 75 bit code devices and everyone realized that 
Stan was right and everything was changed,
including equipment being tested in the field.

I will ask Stan about those times the next time I see him.

Bye for now, Bill Carpenter

I was going through some items and came across my book for the  RA-4000  editing 
controller.  A beautiful device but with no memory  for an EDL.
 
This was probably the fastest editor that I have ever used.  Everyone  loved it 
for doing commercials.  If fact I did one night over 20 in an hour  that were 
cores with product and prices to be filled in the holes.  We had  five machines 
tied to it.  2 VR-1200B's and 4 AVR-2's.  

 
Somewhere I had read that this was originally a 72 bit machine.  The  current 
book has the nomenclature 80 Bit on the instruction book.  Does  anyone know the 
history behind this product and was there a non 80 bit product  released?
