Hi Ed,


I'm continuing to have problems with this list via G Mail. I don't know  if 
you will be able to read this from the Quad List.


Each of these vintage tape format recoveries does depend on the physical  
nature of the tape stock. Generally speaking, A format stock issues are  
compounded by the guide situation (different tape geometry on every guide  
engagement potentially). Except for the VPR-1 transport, the handling of tape  is 
somewhat rough at times. Since it can generally be agreed upon that 1"  
helical videotape formulations were a learning experience at that time from a  
manufacturing standpoint, tape quality out of the box, it's ability to 
survive  the rigors of an A-format transport usage and long-term archival 
survivability  were moving targets in my opinion. Over the years, each tape 
manufacture made  improvements in 1" helical stock (3M the greatest in my opinion). 
When type C  was adopted, then we really saw 1" stock become professional 
with further  improvements.


EIAJ tape stock has not been as problematic for us being a later format  
but it can have it's challenges, especially when Karex is encountered.

We  regularly do type A transfers. We have VR-7800, VPR-7900 and VPR-1's  
in their original A format.  


There never is a lack of surprises with the A format and pre-A  format 
recordings. 


One A format issue is the deterioration of the tape stock. Other  problem 
issues usually point to the lack of basic good engineering  standards when 
the recording was made i.e. the operator did not know  what he/she was doing.


According to Jim Wheeler, the first use of the AST was the 7800  or 7900 
machine although it may have been a prototype only.
