Fun fact: the AMD64 patents have expired, with AMD-V patents expiring this year, so there really isn't a need for an x86 license to do anything useful. All that's still protected is various AVX instruction sets, but those are generally used in heavily optimized software, like emulators and video encoders, that tend to be compiled to the specific processor instruction set anyway.
As far as intellectual property protections go, You wouldn't be able to copy the layout of an old AMD or Intel processor copyright infringement, not that anyone would want to, because it wouldn't be cost effective to use the exact same process decades later. There's no trademark protection, as AMD was unable to register the x86-64 trademark (https://tsdr.uspto.gov/#caseNumber=76032083)
Other than protections against industrial espionage, that exhausts all forms of intellectual property rights in the US.
Microcode is specific to a given implementation, so if you make your own x86 implementation, it's not going to run AMD's or Intel's microcode unless you go out of your way to make it do so. NEC didn't infringe Intel's copyright, because their processor ran different microcode than Intel's, and NEC won that lawsuit.
I did face an additional issue: the DNS is now gated by whatng cartel web engines. It is very hard to register a name without those abominations of software. Everything was working perfectly with the classic web (noscript/basic (x)html) with no credit card only a few years back.
So what I did to help you here was that my browser was easily able to solve the captcha and then I used singlefile extension to get an .html file and then uploaded it to github
IP-locked ISA is something nobody sane would want.
