How about this one?

IMO, the JPI's EDM930 display seems cleaner and easier to spot crucial
information.

Hmmm...IMO, the EI is more clear, plus all the sub-pages are mighty helpful!

Ya gotta remember the first LOP operations were in the large radials and
they were all carbed.

Yup, but most of them also had a big impeller between the carb and the
jugs that tended to stir up/even out the mix before it went bang...

Many also had a single carb for each piston (IIRC) ...or the radial
naturally provide better distribution, so the fuel/air distribution was more
even than with an inline four or six.

Usually only one carb (big stinking carb), but the induction system
was typically a lot "cleaner" with all the intake pipes from the
blower case being same length/bends. In a lot of cases, the exhaust
was much better balanced also.

The big difference was the integral supercharger located in the center
of the induction system (typically with the intake pipes fanning out
from it), stirring everything up and throwing it out evenly...

Yeah, okay, that rings a bell! I still recall multiple carburetors
(Lindbergh's plane had three), but however many, and superchargers as well,
they were centrally located such that the paths were all the same length.
