Possibly simple circuit boards with say a single layer on them will be constructable at home soon. Ie you could print yourself a new c64 board instead of paying gazillions to a source online. If we could get the chinese to duplicate old c64 special chips like the sid then truely c64s could go till the end of time. I read the other day about pushing to mars. More basic computers like 8 bits work particularly well in high radiation areas. Could be just the trick for colonists.
Not to mention 8 bit backups for space craft critical systems. Just a thought. Someone may disagree.
