Should have mentioned previously that I am servicing a Vectorbeam board 
- does anyone have the differences between the Vectorbeam and 
Cinematronics boards for HP Signature Analysis (SA)? Took me a little 
while to notice that D8 doesn't break the same lines for 1 & 16 and 2 & 
15 on both versions. Makes SA difficult at best on the Vectorbeam 
boards. Rather than spending time tracing the differences I'm hoping 
someone here is willing to share with us the differences or the mods 
needed to be made to the Vectorbeam board (or Cine SA tool) to enable 
one to run the Cine SA charts...

As always, thanks!
