====== The M8 Bus ====== The M8 bus design allows using the most advanced ICs that were available at the time, without regard to brand and fully supports DMA with the 6809 as well. Note: The board decodes two bus select signals [[BSEL0]] and [[BSEL1]], only BSEL0 is routed to the M8 bus. The additional decode could be routed to circuits on peripheral cards, using fly wire jumpers, for development purposes. Return to [[:SST-6809:]]
