I'm sure you're talking about arranger keyboards, but...

Not in any particular order:
Minimoog (s/n 10)
Yamaha CS60
Korg Trinity Pro
Generalmusic Genesys Pro S (say, that's an arranger)
Mellotron (2 actually)
Korg MS20
Hammond BCV (best sounding Hammond I have ever heard)
Kurzweil K-250
Clavinet D6
Pianet
Wurlitzer EP200
and more that are not coming to mind at the moment.
