    I have a hobby project with an old CP/M-80 system, where I now would like to disassemble/decompile some compiled code - a ROM and some small executables - into assembly source so I can regenerate the exact same binary. I have an emulator running on macOS.
  5. (Long time TRS-80 users may remember this format as similar to that used by DSMBLR, the MISOSYS disassembler for the TRS-80.) Four different types of address ranges are supported: aaaa one or two bytes at aaaa (two bytes for word data #aaaa) bbbb-cccc a range from bbbb to cccc -dddd a range from 0x0000 to dddd eeee- a range from eeee to 0xFFFE ...

    It is a symbolic labeling disassembler that supports all Z80 instructions and can read either TRS-80 CMD files or Intel HEX files. The Z80Disasm command line looks like this: Z80DISASM [options] [file] The following options are supported:-v: Read file from a TRS-80 virtual disk instead of a Windows directory. -s:
  7. Note that for 16 bit constants, the bytes seem to be reversed in memory. This is because the Z80 is a so-called little endian CPU, where the lower byte comes first. Some other processor families (like the 68000) are big endian and store the higher word first.. So there are 256 instructions only, which makes it pretty easy to disassemble them.
