The MP1 is still available and widely used.
It can be used with an inductive (IMM)or mounted to an MA1 system.
You will need a MI5 interface and other parts to utilize it but you may already have all them.
It would be used for part finding (IE jig location)and part probing, with the ability to update the controller offsets.
Feel free to call me and I can go over it w/you.
