Pulling the characters one by one is not a problem on the 68000. Byte
access is always legal, alignment doesn't enter into it. The problme comes
when you want to access Integer data that is not aligned on an even boundary.
	Ptr bufferPtr;

	...
	nextChar := bufferPtr^;
	bufferPtr := bufferPtr + 1;
for single char data.
