Hello slacker,

Thank you for that information. Recapitulating when data and address bus is shared between SDRAM and other tri-state devices the connection of the SDRAM signals doesn’t change (A0 of the SDRAM must be connected with A0 of the external bus) and A0 of the external bus must be used for the other devices on the bus for byte addressing.

When the hardware is ready to start I will post the results here.
