So, reading the comments here I got the impression that the 8086/8088 order was backwards from everything else before it. Did the 8080 and Z-80 have the same order as the 8086?
But even then, you have worlds converging. The 8086 was (barely) capable of running Unix, whereas the Z-80 definitely was not. Was the 8086 a part of the PDP-11 minicomputer world, or was it part of the 8080/Z-80 world? Well, it was both. Complaining that one world produced an assembler before the other did is... a bit exclusivist. Also whiny.
Neither the 8086 nor the Z80 have virtual memory. The x86 has a larger instruction set and address space (1MB) but as it turns out, early Unix kernels didn't need that much RAM either.
