- jsheard 2y agoHaving dormant hardware which is intended to be unlockable later is a separate thing, which is rarely seen on consumer hardware. Intel tried it a while ago but the backlash was so severe that they gave up and reverted to permanently fusing off the silicon. https://en.wikipedia.org/wiki/Intel_Upgrade_Service https://en.wikipedia.org/wiki/Intel_Upgrade_Service I believe they still have something similar which allows Xeon processors to be upgraded in the field though. Car manufacturers have been testing the waters too, e.g. installing heated seats in every model and making them a paid software unlock for lower end models that didn't have that option enabled from the factory.
- hinkley 2y agoIBM’s problem was going to be inventory, labor, scheduling, and transportation costs. Your mainframe is slow and IBM is going to charge you 6 hours of labor to come out for 90 minutes next Friday, or we can deal with it over the phone. I can’t recall but did IBM use that extra hardware for physical redundancy in case of hardware failures? I know they researched letting equipment die and coming out and replacing it after multiple failures instead of single ones, but I don’t know if they applied that to shipping mainframes, to regular rackmount hardware, or just in Research.
