EUh... My 128D (plastic) has 9V AC... 

Speaking of 128D's (off-topic!): How many 'national' versions were
there of this machine? I've got a German 128-flat, a French/Belgian
128D (AZERTY sucks, btw) (ah well.. I wish it would, actually), I remember 
reading that there was a swedish version too..

Anyone?
