Not only that, but the harmonics were 12-tone equal-tempered!  That's a 
prime reason why nearly every synth B3 emulation falls short.  Only those 
with top-octave dividers or the Voce V3's 91 digital oscillators (do they 
do this with software or an ASIC?) do justice.  

Ah yes... the good old days when you had to oil your "oscillator bank"  
every six months!  Is that analog or what?  :-)  They even had voltage 
control of sorts--just whack wthe AC power switch around for the wildest 
pitch bend you've ever heard!
