Many of the systems that contained these old devices don't have enough ram to run a modern version of freebsd. If you can't update the system to 13, you don't need ongoing ed(4) support. And make no mistake, ongoing support IS the issue -- it costs manpower we don't have much of to maintain old device drivers. -- Ian
