Might be easier to turn the CPU into a daughterboard, like the XLerator and then use modern SIMMs or socketed SRAMs, no?
You'd still need to ensure I/O, ROM, SIO, latches, etc. still show up where they belong. I/O space starts around 0x00FC0000 and ROM at 0x00FE0000, so it will leave most of the 16MB range for RAM (16515072 bytes)
