Motorola MEK6802D5

Hello all, I just aquired a "Motorola Memory Systems MEK6802D5" single board computer. It appears to be a 6802 evaluation or prototyping unit. It has a hex keypad and a 6-digit HEX display. In my old Motorola literature, I can find a reference for a MEK6802D3 from 1979, which appears to be an older version of this. The date code on the chips places it at circa 1980. Does anyone have any information on this unit? Any idea where I can get any documentation or programming info? It appears to be fully functional (at least, I get a display, and I can page up and down through memory examining and changing contents, etc). Any info would be appreciated. ___ __ __ __ _ _ _ _ |_ _|__ _ _ _ | \/ / _| | __ _ _ _ __ _| |_ | (_)_ _ Okanagan | |/ _` | ' \ | |\/| \__| |_/ _` | | / _` | ' \| | | ' \ Internet |___\__,_|_||_| |_| |_| |___\__,_|___\__, |_||_|_|_|_||_| Junction Network Operations Centre |___/ Phone +1 (888) 944-INET
