- This change introduces a full refactor of the interrupt subsystem for the system board (SBD) and the I/O bus (CIO). Interrupt decode should now be significantly faster, and not require an expensive calculation on every step. - The TIMER device has been split into Rev 2 and Rev 3 implementations. - The optional 3B2/400 Debug Monitor ROMs can now be booted by passing the "DEMON" argument to the 3B2/400 simulator BOOT command. Any of the following will cause the Debug Monitor ROM to be booted instead of the standard 3B2/400 ROM: sim> BOOT DEMON sim> BOOT CPU DEMON sim> BOOT DEMON CPU
