    Motorola MEK 6800 D1 Kit evaluation sbc

    Good memory! The D2 kit was indeed more hobbyist friendly including all the necessary logic as well as discrete parts. Documentation was also more complete with app note encouraging modifications and “hacking”. Many hours of learning and fun. Here’s a photo of an unbuilt kit.

    Motorola MEK 6800 D1 Kit evaluation sbc

    There was also a related (similar looking) board called the MES6800 Exorciser Evaluation Board which had mostly the same layout as the 6800D1/6800C PCB but included address/data bus buffers. The MES6800 is actually what is pictured in the thick M6800 Applications Manual and not the 6800D1 (no...

    Adding a serial LCD screen to the KIM-1

    Depends on the video display controller used. My early swtpc video board (percom electric window) uses the CRT5027 controller, and my similar mid 70s Motorola Exorciser system video boards use the 6845 controller. Both video display controllers use memory mapped display memory and incorporate...

    Looking for ALT2480, ALT512 manuals or a scan or just tech info on ports/operations

    That rings a bell, several years ago I asked and paid that seller to scan his manuals for me, as the S-100 ALT-2480 circuitry is nearly identical (except for the bus interface) to the Motorola Exorciser versions of the 2480 I have - EXO-2480, and EXO-512. Here are the PDFs he sent me of the...

    My super minty Intext ICS/Elenco XK-300 M6800 trainer plus some extras

    The book "Introduction to 6800/6802 Microprocessor Systems" by RJ Simpson and TJ Terrell pairs nicely with the 6802D5 trainer. Besides basic intro to concepts, it has nice worked examples and labs utilizing the D5 trainer. Shows up cheaply occasionally in used bookshops / ebay. Also available...

    Why did early home computers rely on terminals?

    There were also early (spring 1976) machines that tried to be "hybrids" between hex display/keyboard systems like the MEK6800D2 and full up systems using a terminal or CRT for display. My second computer after a MEK6800D2 was the Digital Electronics Corp DE68. A 6800 computer that included a...
