The z80 protocol decoder disassembles the instruction stream of a Zilog Z80 microprocessor.
Hardware
KC 85/4
The z80/kc85 directory in sigrok-dumps contains a set of example bus captures of the Z80-based KC 85/4 computer.
The logic analyzer used was a Sysclk LWLA1034.
Protocol
The data bus lines plus the control signals /M1, /RD and /WR are sufficient to display full disassembly. Optionally, the address bus lines and the control signals /MREQ and /IORQ may also be provided.
