Ok, here is a rough diagram of the logic I am considering (this will slow the CPU down to access the 1MHz bus. Obviously a lot of details need to be considered. But as a rough idea this is what I am thinking.

I am working on building a 65816 based computer (for personal use)

Eventual goals include:
65816 CPU up to 14-16 MHz (In Turbo Mode)
up to 16MB RAM (512K on the main board)
Dual YM3438 audio
IEC serial device support
