I have now finished the MIP and the MCP from the home cockpit, the main connection for simvim (ARDUINO and multiplexer etc.) is behind the MCP. Now I have to work a lot more on the pedestal (radio ..). Is it better to extend the data bus until then or should I move each switch etc. up to the SIMvim main board? How long can the address lines (S0 ... S3) be? Or is it not that important?
