Just curious, are there any machine readable schematics or netlists
for the 8/I?

(from my primative understanding an 8/i was made from a few different
flip chips and a *lot* of backplane wirewrap - just wondering if that's
machine readable anywhere)

On another topic, I do SMT all the time.  You do need a few tools - a
nice maginifying lens w/light, tweezers, a very very fine tip (a low end
metcal is very helpful).  A special hot air gun is also helpful for
removing parts with lots of pins.  And if your pcb's are finished with
"hasl" - hot air solder layer I find you don't need flux as much (but it
does help).
