I have 1000s of 60-80s computers and I did plan to open up a museum but it’s probably not going to happen. So I might make art with them. I like them a lot more than modern stuff; the way they look outside and inside, I can repair them and they all work and make lovely sounds. If I would sell them; eBay or specific sites for that specific computer. I traded tons on msx.org and the prices are not the highest but good. Also there is a store in Japan that pays a lot for some types of msx ; I showed my collection of turbo-rs and I could’ve bought a house where I live with the end result. Of course I kept them.
