It's an assembler that takes 8086 mnemonics and produces 8086 binaries but the assembler runs on a Z80 computer. It's a common type of assembler -- all the assemblers I use these days run on x64 Windows or Linux but assemble for other architectures (6502, Z80, SC61860, ARM). > x80 and x86 have quite a lot in common. They do. But they also have some pretty massive differences. If you're trying to run 8080 programs on an 8086 you can translate but you're still getting an 8080 program with it's limitations. You wouldn't write an OS for 8086 that way! It wouldn't make sense at all. I think you need a better understanding of the technologies involved here before you try and defame Tim Patterson.
