[Coco] CoCo3 FPGA project analog boards

[Dave Philipsen]

I realize that and actually I may have misspoken when I said that my build only supported 2 meg.  For some reason I was thinking that Gary had told me that only 2 meg of it was enabled but he might have just mentioned what you have just confirmed; that NitrOS9 only suuports 2 meg.  In any case, Gary will support all iterations of memory and I think he has not given up 100% on the 'new' DE1 SRAM.

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.
