Well, if you want the original 'Dec Fieldservice Oscilloscope', you
need to get the Tektronix 645B. They are widely available 2nd hand,
look at your favourite auction website for one. Proces vary between
$100 and $200.
You sure that's a 645B and not a 465B? I see a number of 465B
scopes, but no 645B.
