No other consumer-grade chip had this as far as I know.
The 8086/88 has status outputs which provide similar information, including which segment register is being used (CS, DS, ES, SS) and the type of bus cycle (interrupt acknowledge, read I/O, write I/O, halt, opcode fetch, read data, write data).
