I'm afraid I haven't been following this thread, but this caught my
interest.  So, I'm not sure exactly what you're up to, and this might
or might not be relevent.

In the May 1988 Rainbow, Dennis H. Weide has an article "Static RAM
Interface" that describes a 16K SRAM expansion pak that lives in the
usual C000-FEFF cartridge ROM space, but can be read *and written to*
normally.  

Is that of any use to you?
