I would like to add the caveat that if, say, someone
is using a
hyper-super modern number-crunching x86 PC to do DSP-stuff
for the express purpose of doing data recovery from DECtapes
or 7-track magtape from 40 years ago, that IS INTERESTING and
probably on-topic. Not so much for exactly what the modern
computer is, but more for what it does and how it gives a window
into the old media.
I would agree (and I seem to remember similar 'exemptions' under the 10
year rule). The idea of using a modern comptuer as a tool to help with
preservation of old software/data seems 100% on-topic. As would be using
such a machine as, say, a mass storage device for an old computer (so we
can talk about TU58 emulators here, even if they run on modern PCs).
