That's what I have.  It's a barebones 7603.  For example, Tek offered
a "readout" option, i.e., display the sweep and vertical sensitivity
settings on the screen.  That was probably pretty common, but the unit
I have didn't come with that.

No harm done, I've never had it before, and since it was an option I
wouldn't call it cheating if someone sells a unit without the option.
