I believe the Mac Plus was the last model to have the D-SUB 9 for its mouse.
The original Mac 128 had the 9 pin connector but it had a square shape
as opposed to the later connectors. You can see the difference in this

right is the original Mac 128K and the one on the left is a later
version. My question is how much later :).
