After looking up some component data sheets, I've found myself wondering a few things: 1) The H8/3292 pin 42 connects to the D43256B pin 23. According to data sheets, this is A6 from the H8 and A11 on the RAM. Both data sheets show address numbering (...) (23 years ago, 15-Feb-02, to lugnet.robotics)
