Engineering sample of Motorola 6800. In the early days Motorola used XC prefix for engineering prototypes, this prefix was changed to "PC" for more recent processor families. It seems that the speed designation of the XC processors was different from production processors - production parts had speed designation in the middle of the part number, for example, 68B00 for 2 MHz parts, while the engineering samples had it at the end of the part number. |  |

MEK6800 Evaluation Board
Motorola produced an evaluation board (MEK6800) based upon the 6800 CPU around 1976-77. This had a separate module with a hexadecimal keypad, hex display module (using 7-segment LED displays) for user data entry and output and an audo interface for saving/loading programs/data from standard audio cassette.
Evaluation board had a backplane conenctor as well to match an industry standard bus.
I built up a reasonable PC for the time with an EPROM programmer, ASCII keyboard, video display card driving into an ex TV station green-screen monitor, and extra 8KB of memory.
I had Integer-only BASIC programming language which ran in 4kilobytes and ran a number of useful and games programes on it.
