[Coco] Programmable Sound Generator Cart for CoCos

[Zippster]

Not really, but this is a pretty simple scheme.  The upper portion of the address to the bank in the 
memory chip is contained in the register.  And in a dual-chip setup like this, a bit to determine
which chip.

For instance, on the MC-10 board (16K banks) it goes…

Register data for a banked area;
	- bits 0..4 = upper address of chip memory (32 values, 32*16=512)
	- bits 5..6 = not used
	- bit 7 = chip select (FLASH or SRAM)

So, you can see, this scheme is limited to 128 banks when the MSB is used for a chip select,
assuming an 8-bit register.  Sufficient here though.

How does the CoCoFlash work?
