*4 - Since both (Z80, 8085) were launched in March 1976, it's not very likely that this was without early knowledge of the changes Intel did. they move data between the same register, thus making it effectively as well NOPs since MOVs don't trigger any flags. *2 - All of them do trigger flags, so while the result is forseable, it may be used on purpose to prepare some flag. Faggin somehow knew (*4) that the 8085 would as well not touch any of these opcodes, so the level of incompatibility between Z would be about the same as Intel introduced with the 8085 The only reason I can think of is that Mr.

Especially since the prefixes take away much of the advantage of many of the 16 bit opcodes.

They would relieve plenty of room from the 8080 code set. But I always found it strange why they didn't touch the MOV-NOPs (*3) which would have brought 7 additional opcodes. Likewise, to a lesser extend, the 'flagging' NOPs ANA A, ORA A and CMP A (*2). *1 - I understand that the A zeroing opcodes ( SUB A/ XRA A) haven't been touched, because some used them. Only on Assembler the above mentioned different 'spelling' is visible - think of it like Mancunian English vs.

After all, on binary level all 8080 is as well valid Z80. 8 hours ago ODA is an online disassembler for a wide range of machine architectures, including: Alpha, ARM, AVR, Intel x86, Motorola 68000, MIPS, PDP-11, PowerPC, SPARC, Z80, and more Upload a Windows PE file, ELF, or raw binary and then view the disassembly and object file meta date such as symbols and sections. Will the 8080 tests be valid 8080 assembly code? Therefore I obviously need to disassemble it using a Z80 disassembler. The reason I'm asking is because Supersoft Associates' CPU Diagnostics II program from 1981 contains both 8080 and Z80 code it checks which CPU it's running on in the beginning, jumping to CPU-specific testing code. So essentially it will produce an all Z80 Assembly source code (Z80 column), but certain operations are not used in 8080 sections. No hidden gotchas, but then again, it will come out as Z80 assembly, not 8080, as the Zilog changed the words of the assembly language. Likewise the 'alternate' opcodes CBh/ DDh/ EDh/ FDh that all produced JMP and CALL on the 8080 became prefix bytes (*1).Дoes this mean that if I disassemble an 8080 program (which doesn't use any undocumented opcodes, naturally) using a Z80 disassembler, will the result be correct 8080 assembly code? Or are there any hidden gotchas? err, no, they placed them on redundant opcodes.ДЇor example the whole 00-xxx-000 group were NOP instructions for the 8080, while Zilog only left 00h as NOP, while the others became jumps (and EX).

It adds a bunch of new instructions, but places them all in unused (well, undocumented) opcodes. The Z80 is 'binary compatible' with the 8080.
