Yes and apparently there are at least two dialects for 8086 assembly, one from AT&T and the other from Microsoft.

Apparently they are mapping different mnemonics to same machine code and using different syntax for addressing modes.

Furthermore is assembly programming only fun if there is a macro language included.

Back in the time of my 68000 jobs this made a lot of meta stuff non portable between different assemblers.

Friend of mine claims that he can still read Z80 machine code in hex format.
