Re: assuming the builder could get real solder
Perfectly available. Very fine pitch ICs in consumer gear is permitted Tin/Lead (because the tin would grow dendrites). Certain aerospace and military parts has to use it too. The lead free stuff isn't reliable.
I've loads of chips that old. Though I'm not sure why. I think some of the exact same RAM if someone wants it.
It's likely much easier than forging good banknotes or old masters and actually such a product would be an authentic counterfeit rather than a forgery.
