For supporting both CP/M and DOS, you can skip over an 8080 jump instruction using a single extra byte: 80 C3 xx xx The first instruction will be harmless on both processors, and even have the same mnemonic: it decodes as either "ADD BX,xxxx" or "ADD B"!

small correction: the first byte is 81, "ADD C" on the 8080
