In the early 1990s Motorola produced an evaluation board kit for the 68HC11 with several UARTs, RAM, and an EPROM. The cost of the evaluation kit was $68.11.<ref>[https://groups.google.com/forum/#!topic/comp.dsp/4uquwRWrFno ''comp.dsp. 1 Oct. 1996'']</ref>

The standard monitor for the HC11 family is called BUFFALO, "Bit User Fast Friendly Aid to Logical Operation". It can be stored in on-chip ROM, EPROM, or external memory (also typically EPROM). BUFFALO is available for most 68HC11 family derivatives as it generally only depends upon having access to a single UART (SCI, or Serial Communications Interface, in Motorola parlance). BUFFALO can also run on devices that do not have internal non-volatile memory, such as the 68HC11A0, A1, E0, E1, and F1 derivatives.
