Talisman is a fast timing-accurate simulator for an 88000-based multiple-processor machine. Talisman provides both user-mode and system mode simulation and can boot OS kernels. Simulation is reasonably fast, on the order of a hundred instructions per simulated instruction. Talisman also does low-level timing simulation and typically produces estimated running times that are within a few percent of running times on real hardware. Note that e.g. turning off dynamic RAM refresh simulation makes the timing accuracy substantially worse!
