(Same person asking about Commodore 64 case) is there any good sites for finding older computers? I saw some on Amazon and eBay but they've screwed me over a few times and I'm not sure if I should trust that.

craigslist is literally your best bet. next ebay

there isn’t much of a market for them. you have to kind of go on adventures to get really cool stuff. you’re competing against very competent people buying vintage computers on the internet
