just play I have an old tektronix scope too (564) they're great scopes.

Mine is late 70's... Yours being a couple of model numbers lower shouldnt be 
much behind that....
Mine will be staying with me for a LONG LONG time, since I reseated my 
timebase generator and input modules (mine has pluggable modules) The traces 
are sharper and the timebase now locks, first time everytime, its superb!
