The emulator implements 64K of memory for the full 16-bit address range. Interrupts (on execution of a BRK instruction, code 00) will always trigger a trap. These observers may by activated/deactivated both individually and globally. Traps may observe the value of any of the 3 main registers (AC, XR, YR), watch for an under- or overflow of the stack register (SR), or monitor for the program counter (PC) by setting a breakpoints. You may set any number of traps or breakpoints, which will be monitored in continuous run mode.

Click a registers label to set its value.

The cycle time display shows the clock ticks of exceeded CPU time (including extra cycles for branches and page transitions). The line disassembler shows the current value of the program counter (PC), the content of the according memory address (the next instruction followed by the operands, if any), and a disassembly of the respective instruction. The status register (SR) holds the following flags (from bit 7 to 0): N
