A multimeter will do nicely with static signals. A logic probe can help as well. Especially if the computer "hangs" then there should not be much activity on the bus. On zimmers.net somewhere there is a BASIC implementation of the IEEE488 protocol for the PET, that you could stop in any place of the protocol (watch the timeouts though) to monitor the state of the bus.
