My old MSX programs and data, dated back to 1985, are all backed-up in modern media (my several PCs hard-disks, some CDs, DVDs and a couple of thumb-drives). Besides, I keep three MSX machines (don't know if they all are still usable), and images of their EPROMs together with the other data. Even if all the machines break, there are perfect emulators available (in my opinion, BlueMSX is the best). The same for my PC data back to the times of university, when I got my first PC computer (a 40MHz AMD 386DX-40, of which I still have the boards). In fact, probably I will never need that data, but it is reassuring to have it available.
