Motorola 68HC11

The 68HC11 (6811 or HC11 for short) is a microcontroller (µC) family originally from Motorola, now produced by Freescale Semiconductor, descended from the Motorola 6800 microprocessor. It is a CISC microcontroller. The 68HC11 devices are more powerful and more expensive than the 68HC05 microcontrollers, and are used in barcode readers, hotel card key writers, amateur robotics, and various other embedded systems.

FAQ.
There is an opcode simulator for the 68HC11, by Ted Dunning ted@nmsu.edu. Interrupts, hardware I/O, and half carries are still outside the loop. Adding interrupts may require simulating at the clock phase level. Version 1.
