Yup, a FW enclosure is an idea - though my current ibook only has a USB port... are there dual USB/Firewire enclosures?
And... this is stretching it... is there an enclosure that will handle multiple drives?
eBay... yeah, that's an option. Have never sold, only bought. Maybe I'll find someone to trade me a new 2000-series Newton, or a motherboard for my Mac Portable!
