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.
