> The golden age for me is any period where you have the fully documented systems. Hardware that ships with documentation about what instructions it supports. With example code. Like my 8-bit micros did. And software that’s open and can be modified.

I agree, that it would be good. (It is one reason why I wanted to design a better computer, which would include full documentation about the hardware and the software (hopefully enough to make a compatible computer), as well as full source codes (which can help if some parts of the documentation are unclear, but also can be used to make your own modifications if needed).) (In some cases, we have some of this already, but not entirely. Not all hardware and software has the problems you list, although it is too common now. Making a better computer will not prevent such problematic things on other computers, and not entirely preventing such problems on the new computer design either, but it would help a bit, especially if it is actually designed good rather than badly.)
