hi there, nice pedigree

To get your Mac or PC to see the files on the brain, you need to press the top-left button above the screen, straight after switching it on - this puts it into "USB Mode". It should then mount as a disk on your mac / pc.
By the way, when you switch on your brain, what OS version do you see? You might want to check out the
resources page for useful links to the manual, setting up etc.
cheers
Tom
