[rescue] EPROM lifespans and archiving (WAS something else)

As of the mid '80s, the given lifetime of current EPROMs was listed as "at
least 25 years," so it is important that collectors/enthusiasts start copying
the firmware down. The bad part is that it's difficult - you can usually get
the main machine firmware easily, as it's often mapped into the memory space,
but the firmware for peripherals can be difficult.

Regarding legality - I'm not exactly sure about computer software, but there
is a time-honored and government-approved fair use provisio for legitimate
archive libraries to make copies of things, and even to violate the DMCA if
necessary to do so. There are, however, limits on what a legitimate archive
library is.
