[Coco] Is the 6809 flawed?

[Melanie and John Mark Mobley]

A 8-bit signed shift right will look like this:
-128, -64, -32, - 16, -8, -4, -2, -1, -1 , -1, …

A 16-bit signed shift right can look like this:
-128, -64, -32, - 16, -8, -4, -2, -1, -1/2 , -1/4, -1/8, -1/16, -1/32, -1/64, -1/128, -1/256, -1/256, -1/256 …

0xFF.FF => -1/256

-128/(2^15) = -1/256

-128/32768 = -1/256
