Welcome / добро пожаловать to my Tech-Channel.
Here you can and should ask me, about the logic level of CPU's or other controllers.
The main problem with such a hobby is that there is hardly any information about it. And its expensive of course.
By the way, I know that my 8 bit adders are no CPU. But with all my other components, its really close to a central processing unit.

No advertisement here, I know how annoying it is :)
