But I wasn't talking about anything other than the TI-85's link port.
Of course other devices switch at different logic levels, but that has
nothing to do with the TI-85.  My point was that you cannot get the
TI-85's link port to switch at different voltage levels without
internally changing the components, which for all intents and purposes
is impossible.

Besides, the idea of "high" and "low" switching instead of on/off
switching has been around forever.  It's not a new thing.  They just
used a better sub-micron technology so that they could do it even
faster.  The idea of the totem-pole transistor pair or the BiCMOS
processes are very similar.  I guess the latest processors, though,
are just now using it to its full potential.  And reguardless, just
because the clock speed is twice as fast doesn't mean that system
performance will be twice as fast.  The PII has a much faster clock
rate than the PPro but in the end it's not more than 15-20% faster
