I was using email to communicate with folks in hawaii back in 1978
on PLATO systems. PLATO[*] predates the internet by 25 years. We also
had IM (instant messaging) in the 70's (TSS-8.24, MPE/3000 and
[*] Had the best computer games, too. Plasma panel graphics (monocolor)
and nationwide multiuser access allowed players from all over the country
to compete in space games (Empire) and dungeons-n-dragons (DND) using
(rather massive) graphics terminals.
Why do you introduce the additional criteria "grid power". Scott only says
It is impossible to communicate without power. Even "by foot, horse,
runner, shouting" all take power.
Scott needs to better define his question.

You fire up the amateur radio transceiver in your car -- or the one at
home for which you have well-maintained standby batteries.
"When all else fails... There's Amateur Radio."
Amateur Radio was used when the cell-phone towers on top of the World
Trade Center were put out of action. Amateur Radio was used in the
search for the debris from the space shuttle that was scattered over
remote areas of Texas with no cell-phone service.
Sadly, most stores are computer operated. Need

Years ago, I heard of one family owned store doing
shopping by flash light, pad, and cash only. During
a power cut. Made sense, to me.
Last power cut, the convenience store near me had
two candles, and a very weak 2D Never Ready flash
light in the place. I chatted a few minutes, and
he didn't sell much during that time.

We maintained a lot of "point of sale" and it was always funny to
watch them try to run the store without the registers. Older workers
seem to do fine but the "kids" (up to 30 sumpin) needed a calculator,
just to make change. They were still slow and confused by the process.
The fact that nothing was priced made it even harder.
I have seen grocery stores where they had a manager just stand there
and dicker with the customer, guessing how much a cart of groceries
was worth. The customer usually had a better idea than the manager but
they usually started low.

After Hurricane Ike, I was with a neighbour who went to Walgreen's

borrow one of my wind-up radios.
