Quite right - you wouldn't even see (much of) a difference between a 
CoCo3 (of any memory) and a 32K/64K CoCo1 or 2... [DS]ECB can't use more 
than 32K RAM.

The CoCo3 did have some commands that could access memory outside that 
32K (LPEEK/LPOKE) and the CoCo3 graphics pages were kept outside the 
"original memory map" and was paged automatically by the GIME chip.

For a CoCo3, you could do a LPOKE to an unused memory area outside the 
"normal" 128K address space, then LPEEK that address to see if the value 
was the same; there may be other ways to verify but I can't think of a 
better one right now.

HTH!
