[Coco] CoCo3 FPGA project analog boards

[William Astle]

In the interest of clarity, Nitros9 doesn't support more than 2M so that 
isn't a good metric to determine whether both chips are active or not. 
Basically, even if you have 4M, Nitros9 will only report 2M.

In fact, I'm pretty sure that the preliminary version I'm working with now with the analog board does not use the onboard SRAM.  It's only presently using one of the two meg chips and when I boot NitrOS9 it reports 2 megs.
