[Coco] Bubble Memory

[Bruce W. Calkins]

One of the limits to the CoCo 1 & 2 memory expansion was the inability 
to shift small-to-medium sized blocks in and out of the memory map.  
Basically it was limited to 32k mapping blocks.  This applied to the PBJ 
128k & 256k expansions too.  That said; RAM Disks really did speed up 
many processes.
