I'm curious. Are there actually customers out there who are running a machine that is older than the minimum required for OS/390 R10 (namely machines which support the initial relative/immediate support)? We know that such customers would not be running a supported level of z/OS, but they might be running something other than z/OS, or something that is no longer supported.
