So the bottom line is that, although building a RAM card for the IIgs larger than 4MB is more complex, the 65816 _can_ directly address up to 8MB of RAM. That could all be used by an operating system, if needed.
The 816 is capable of directly addressing 16M directily through it's internal address registers. it can be done linearly if you use a latch for the upper 8 bits of the 16 bit address. The lower 8 bits of the address is the 64k...
Again, to build a larger ram card means dulpication or bypassing the Memory manager/CYA.
