I notice a lot of people have suggested "use an emulator," as if that had never occurred to the OpenBSD developers before, but nobody has volunteered to verify that the available emulators are good enough to actually replace real hardware.
Also, I don't understand why anyone thinks emulation would reduce the power bill. Even assuming the OpenBSD developers were interested in using emulators it's not like they're just going to install one and then power down the old machines. The old hardware would still run while they're validating the emulators, and that process would probably take a really long time. So there's no potential cost savings for a really long time, and in the meantime some of the devs are now distracted from actually working on OpenBSD because they're so busy verifying the accuracy of the emulators.
