Hi bernard, at the moment it is running 10.4 with Fire wire, no scsi. It is 100/240 volts, 50/60 Hertz. A mac Mini G4 wich is running the scanner at the moment can be added.This way you can work normally on your main system and have the Mini do the labour.
Thank you Peter, still thinking.

Can it scan 11x14 inch negatives?
Cheers,
Bernard
