Just use emulation
I know I'll get a bit of shock and horror for this, but last year I 'wasted' most of a day playing with my old 8 bit MSX, and for the most part it's not worth the effort.
Use emulation, you won't notice the difference, and the save states will be a boon. 8 bits really are starting to look a bit creaky, although 16 bit graphics are still fluid and sufficiently fast they're not showing their age as much.
The one exception was Boulderdash, which still plays amazingly well despite the ageing graphics. Elite is now in the category of brilliant for the time, but not standing up to modern tastes. I'd probably give a pass to the Magic Knight series too, and that's one set of games that had a special Spectrum 128 version and is best played on there.
