-The ECB 6x0x-ATX/6U (VME) board is a single board computer supporting the Motorola 6809, 6802, and MOS Technologly 6502, all at 2 Mhz .  In addition to the processor, ROM, and RAM, this board includes all peripherals required for stand-alone operation including serial, parallel, Propeller-driven video output/​keyboard input, and SD card storage. ​ The board layout supports mounting in a standard ATX case and use of a standard ATX power supply connection, as well as attachment to other N8VEM peripheral cards via an ECB connector, in which case the board can fit in a 6U/VME chassis. ​ Prototype testing has been completed and a first run of production Revision 2.00-013 boards are currently in fabrication.+The ECB 6x0x-ATX-6U (VME) board is a single board computer supporting the Motorola 6809, 6802, and MOS Technologly 6502, all at 2 Mhz .
