Technological Arts makes a variety of low cost 6812 products suitable for teaching laboratory classes. These boards are convenient because they can be inserted directly into a standard protoboard. See figures 1.28 and 1.47 in the book "Real time Embedded Systems" by Jonathan W. Valvano. Notice that the Technological Arts boards have a male connector that plugs into the student's female socket. If the students purchase their-own protobaord, then the mechanical "wear and tear" occurs on the inexpensive protoboard and not on the relatively-expensive microcomputer board.

The Kevin Ross BDM-12 is a debugging interface between the PC and the Adapt812. It allows us to download programs, view/change registers, view/change memory, single step, and run software. If you have a logic analyzer for debugging, you can use the BDM-12 to modify the MC68HC812A4 mode so that the address and data bus are available on the Adapt812 H2 connector. With Windows 3.1, you will run Kevin Ross’s DOS-level DOS12.EXE program. With Windows NT or 95, you will run Kevin Ross’s DOS-level DB12.EXE program.
