Korg Polysix, Poly61
Roland Promars, Jupiter 4,6,8, Juno 60,106, CR-78, CR8000
Yamaha CS-20M
Kurzweil K2xxx series
Rhodes Chroma
PPG Wave
Oberheim DMX, DSX, OB-X, OB-Xa, Xpander
LinnDrum, Linn9000
Böhm Digital Drums

that have (regular) battery compartments for their memory backup batteries and of course your TR-909, TR-808, SH-101, DR-55 and all the other synths that take AA, C and D cell batteries.
