Sadly I can't even find Pentium 3's in China, let alone Pentium 90's or 486's. I had a Pentium Overdrive 133 whose pins I accidentally broke after dropping it 15 years ago. Fortunately we have Dox Box or else I would never have been able to replay Privateer II and enjoy all the ridiculous bugs in that game.
Edit: this is embarrassing. Right after posting I can't find them I found 486's for 10 to 20 USD, depending on speed and performance. 486DX5 133Mhz are going for around 20 USD with boards for about the same but EDO RAM is ridiculously expensive.
