I don't know if it qualifies for the contest, but I wouldn't mind using my Apple //e to browse web pages served by my Mac mini. I'll need a super serial card, though first.

Planned layout: Apple //e (SSC) -> Power Mac G3 -> Mac mini

1983 - 1998 - 2008 ... that's a good span, I think.

No Ethernet except for G3 to Mac mini. G3 will be running some sort of bridge, I suppose.
