LocalTalk's pretty cool... I used to hook in old ethernet-less Macs to the home network using my IIfx as a bridge. Slow as molasses though!

Then again, Econet was even slower! BBC Model B was a neat system - first computer I ever used (not counting the Tomy Tutor Play Computer!). They're what the Apple II would have been like if anyone other than Steve Jobs hadn't designed the case.

Cheers, Ben.
