Sounds more like an IBM thing. Same hardware, two different performances (and rental rates), depending on whether the jumper was installed or not.
Other computer companies (I worked for Data General) did similar things. Look for the chips covered in epoxy. Those are the microcode ROMs which define your instruction set. Change those and you get scientific hardware multiply and divide instead of commercial instruction set.
