It's absolutely fine as a slave but if setup as a bus master it would have to be modified to pass control to another slave.  (Its address, data, status & control lines would have to be inactivated by the slave when it has control)  The IEEE-696 is unclear who does this,  but normally the bus master inactivates its own lines.   Except for the similar 8088 our other CPU boards have the appropriate circuits."
