Vintage Compters is easy.
 A vintage scope of the correct era for the machine when it was
 manufactured, of course!
  
 Mine is a Tekronix RM-503.  I also have an old RCA scope, plus a Kenwood
 Service Monitor scope (SM-220) that can handle 1KW of RF at up to 150
 Mhz. 
I have a 100Kc (kilo-cycle) Heathkit 'scope.
