No there isn't such a thing. I asked the same question a few months ago.
The answer was that the 65816 just not really designed to easily be able
to do this (i.e., no memory management) and that the IIgs Memory Manager
already was doing a good job of freeing up memory (much better than the
Mac I was told) so that "in a way" the IIgs already performs some of the
tricks which a RamDoubler program would do.

However, I just read about RamDoubler for Windows. It apparently takes a
slightly different approach than RD-Mac. It increases the percieved 
heap size for each program from the Windows 3.1 allotted 64Kb to 128Kb.
Apparently, this helps a great deal on a Windows machine to eliminate
the 'Out of Memory' type of problems. I assume that the PC is not really
short on memory but that Windows heap (stack) is out of memory.

I was wondering if something similar could be done on the IIgs. Perhaps
a RamDoubler IIgs which does some intelligent stack swapping to free up
memory on the stack. At first glance I don't think this could be done
but I thought I'd throw out the idea and see what others may think.
