Just clean it, there's no need to recalibrate it !

You can't. To cold-boot switch the power off and on, or press reset
and type PR#6 from the basic prompt to reload the DOS.

No it's not. But it doesn't matter as long as the ROMs are the correct
ones.

Bill and Paul Allen were in Albuquerque back then, very busy writing
BASICs for every new computer made. I believe it was Paul who wrote
the (6502) AppleSoft Basic... And this one in ROM is in fact the 2nd
version they made for the Apple II. The first had some different
commands like PLTG.

People were complaining that it was too easy to hit RESET by accident,
as it was so close to, right above the RETURN key. Then Apple fitted a
spring under the RESET key so that you needed to push it much harder
to RESET. Still later on, the keyboard circuit was modified so as to
require pressing (by flipping that switch to CNTR) control at the same
time as RESET in order to reset. Also, in the first Apple IIs the
power light looked like a key, and people often tried to turn the
Apple II on and off pushing hard on the power light... hehehe
