It is really a read followed by a write of 0, so in theory harmless (like 6502 reading a second code byte even for one-byte opcodes).
However, write-only Amiga hardware registers interpret a read...

Different design, same instruction set ? But we have this already. Perhaps 68020-30, 68040, 68060 fare somewhat better than old 68000 ?

And then ? It is just that 6502 uses 1 clock out of 2 (and it does that by design !), 68000 uses 1 out of 4 (probably same), and ARM saturates the bus without any regard to dma or whatever.
