It's just sentimental value for my first computer.Here you go ZX80. Odd how you can pickup a working ZX81 for £20
We can understand that hundreds of thousands of Pentium Pro can be interesting.The gold content of some older parts is of greater commodity value than the market value of systems that age, and the PC gold scrap business has been a thing for a long time.
Tried to build a retro system around a Pentium Pro a while back and was surprised that the cheapest I could find them was $50 a pop. Turns out that anything lower than that was gobbled up by recyclers...because a Pentium Pro has a full gram of gold in it.
A full gram of gold?! All you need is a little nitric acid, some hydrochloric acid, mix them in a 1:3 to make some aqua regia and throw the chips in. You can then crash it out with sodium sulfate, iirc. Yeah, those would be gobbled up quick.The gold content of some older parts is of greater commodity value than the market value of systems that age, and the PC gold scrap business has been a thing for a long time.
