I have a 10 year old MacBook that I keep mainly because I can plug my Nikon Coolscan scanner straight into it with its Firewire cable. Lately my old MacBook is starting to die but my Coolscan is still working fine. After a lot of googling as well as looking at this site I'm totally confused if Firewire/USB adapters actually work. So what I need to know is, if I buy a new MacBook, can I hook up my Nikon Coolscan to it and if so, how?
