How hard would it be for someone far more competant than me to rig
something up to just sample the data stream from such a drive and save
it to some form of modern media?

Forget needing to understand/read/modify the raw saved data for the
moment - the important thing is actually having the data outside of a
drive which could fail at any point.

Given the raw stream, make/model of drive, and (where necessary, if just
knowing the machine isn't enough) make/model of controller to which it
was attached, would that be enough for someone to stand a reasonable
chance of interpreting the data at some later date?

If so, it's better than nothing right now. This of course assuming that
sampling the data is the easy bit and interpretation/playback is the
hard part!
