I'm thinking of emulating a x86 CPU in Scratch. Then we can make Scratch run anything that compiles to x86 assembly.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.

Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.

Whoops you did say GNU/Linux

btw Android uses Linux but's it's not GNU/Linux because it doesn't have any GNU software

I'm fairly certain that most of the base stuff that Android uses is actually part of GNU

I'm planning a 6502 emulator so I can run a BASIC ROM, but I don't have time at the moment. I'm going to need to write a program to generate scratch json for the CPU core, so I can inline as much code as possible e.g. the code for the different addressing modes.

I have the start of an Intel 8080 emulator. All of the instructions except interrupt related ones are implemented, but they haven't been thoroughly tested. I don't understand how all the stuff with the IO pins work, and it has no interrupt system or peripherals.

How similar is the 8080 to the 8086? Does it have an IVT?

I'm not sure if it has an IVT. In fact, this is the first time I've ever heard of IVTs. I am betting that it doesn't have one.

I don't know all of the differences. An easy one to point out is that the 8086 is 16-bit. Wikipedia lists some similarities in this section.
