370 assembler is the generic name for programming IBM mainframes using the assembler programming language. The S/360 and the S/370 are no longer made by IBM. They have been supplemented by the S/390.

There are no physical MIX computers, yet. MIX is a hypothetical, instructional computer construct, a virtual computer in a book, invented and intended to teach fundamental and low level computer programming, via algorithms. MIXAL is an acronym for MIX Assembly Language, an instructional language, for use with the MIX computer. MIX and MIXAL were first defined in Donald Knuth's highly influential and acclaimed: The Art of Computer Programming (TAoCP), Vol. 1: Fundamental Algorithms, Addison-Wesley, 1973. The books in the Art of Computer Programming series are widely viewed as the most important computer programming texts ever written. All programming examples in the series are written in MIXAL. MIX is an example of an old style CISC (Complex Instruction Set Computer) processor, and is somewhat dated. Knuth is replacing the MIX architecture with a modern 64-bit RISC (Reduced Instruction Set Computer) variant named MMIX, and new language named MMIXAL. While this all started as a book, a growing body of software implements MIX emulators, MIXAL, and MMIX. Interest in this topic is growing. Someday will there be physical MMIX computers?

This category holds links on Assembly languages that run on computers, PCs and otherwise, using Intel and compatible x86-based architecture central processor units: CPUs. Main members of the Intel x86 family: 8086, 8088, 80186, 80286, 80386, 80486, 80586 (Pentium), 80686 (Pentium II), 80786 (Pentium III), 80886 (Pentium 4), and more to come. Some x86 compatibles: AMD, Cyrix, Transmeta, Winchip, etc.

The 8bit Zilog z80 processor was quite widespread in the late 70ies and early 80ies as CPU for business and home computers. Nowadays, it's mainly used in measuring and controlling for various purposes.
