[Coco] [Color Computer] Re: POKE 65495,0

On the Coco 3 the memory array would be a three deminsional array. For 512K 
size the array would be 256 rows by 1024 columns by 16 bits deep. For the 4164 
DRAMs used in the COCO2 it would be 256 rows by 256 columns 8 bits deep. 

Due to the array that the ram is organized on you would startt at $0000 and 
increment every 256 bytes. Thus $0000 then $0100 and so forth up to $FF00.
