Obviously earlier units use discrete oscillators for the top 
octave...usually when I see 'what are top note generators' though I'm 
thinking of an all in one unit.  Discrete oscillators are found in

*Most combo organs before 1970 ish.

* Rolands early electric pianos

* Freeman string machine has two banks of them plus a tos chip to get 
discrete vibrato control on each.
