Motorola MEK6800D2

The MEK6800D2 was a more self-contained 6800 evaluation and training system with hexadecimal keyboard and display facilities. It allowed users to enter, inspect and execute machine-code programs without a separate computer.

Widely used in teaching and product development, it made Motorola’s architecture accessible through a compact single-board format.

Notable Features

• Integrated hexadecimal keys and LED display supported stand-alone operation.
• Expansion connectors exposed the 6800 bus for memory and peripheral experiments.

Historical Significance

• Widely used in teaching and product development, it made Motorola’s architecture accessible through a compact single-board format.

Collector’s Notes

• Check the keypad, LED display, monitor ROM revision and power requirements before operation.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
