I'm sure you're correct about all the voltage analysis, except that "harder"
from the above must not equate to "cheaper", since you don't see any computers
with Universal Parallel Bus ports...

/Something/ about parallel interfaces obviously makes them more expensive than
serial for the same speed, and I didn't see anything in your post that
explained /why/ "High speed drivers are expensive" compared to serial ones.
