Re: A 6809 Single Board Computer

I'm not not sure if I understand. I know the input pin 1 (A) R/W, pin 2 (B) A14, pin 3 (C) A15, pin 4 (nG2A) 0V, pin 5 (nG2B) A13 and pin 6 (G1) E but the output I don't understand what do they hook up to? UPDATE: I want to play dungeons of daggorath threw the expansion header but there is no CART/.
