A friend of mine told me that IBM did this with their 1130 minicomputers, back in the day. You
could purchase a "speed upgrade" that doubled the computer's speed. The "upgrade" consisted of
changing a jumper, which took a flip-flop out of the clock line.

This is so common there's even a term for this: "mid-life kicker".  This applies both to doing
a product upgrade in middle of a product's lifespan (which is hardly controversial), and also,
I think, to the idea of "slugging" a product at launch and remove the "slug" for a fee when
doing the upgrade.

While this looks rather insane to some people, it is quite a sensible business practice - the
company can sell the initial product for a somewhat lower price maybe, and grow the market,
then release the faster/better product via upgrade without actually shipping new hardware to
existing customers.  Overall costs are lowered, and in a competitive market both the new and
old product should cost less than shipping an entirely "new" product.

Of course it does depend on customers not finding, or being unwilling to mess with, the
"slug"...

IBM practiced this across their MVS mainframe range for many years. Their customers didn't feel too upset, as they were basically renting MIPS. At original sale IBM would ship bigger iron with some CPUs either clocked slow or disabled. Then the customer would pay more, a "screwdriver upgrade" would occur, and the customer would IPL (reboot) into a faster machine.

The benefit to the (typically banking and government) customer was simple. A mainframe "forklift upgrade" takes about two years of planning to minimise risk and disruption. An IPL takes about eight weeks of planning.

These days, even turning a screwdriver is pretty expensive, so this kind of price discrimination is done with cryptographic keys -- you pay your money and the vendor emails you a key that brings the dormant or underutilized hardware to life.

Sometimes you can downgrade again later too.
