MEK6800D2
The MEK6800D2 was a development board for the Motorola 6800 microprocessor, produced by Motorola in 1976. It featured a keyboard with hexadecimal keys and an LED display, but also featured an RS-232 asynchronous serial interface for a Teletype or other terminal. Data and programs could be loaded from and saved to an audio cassette tape. There was an on-board monitor program called JBUG (analogous to an operating system on a modern computer) fitted in a 1K byte ROM, and the maximum RAM capacity on board was 512 bytes, but this could be expanded via the Motorola EXORciser computer bus interface.[1]
The hardware consisted of two circuit boards. The keyboard-display module contained a 16 key (hexadecimal) data entry section, and eight function keys labeled M, E, R, G, V, N, L, and Pl along with a 6 hex digit LED display. The keyboard-display board connected to the microcomputer module by a 50-conductor ribbon cable.[2]
There was also a parallel bus interface for general purpose I/O.
Another popular monitor program for this system is called MIKBUG.
