Your machine needs to support for at least the z/Architecture, Architecture Level Set 2." That really, really sucks. That means most of the worlds operational mainframes (the ones that will eventually be rotated out of service and be available to people like us) won't run it. I take this to mean that Debian no longer runs on a real S/390 machine but requires a zSeries of some sort. Well, they're still very much "real S/390 machines" in every way. Does that work with Hercules? Yes, Hercules implements both version of the z/Architecture. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
