In October, 2008, Sine Nomine Associates released the first "prototype" (it lacks a number of features such as [[DTrace]], [[Solaris Containers]] and the ability to act as an [[Network File System (protocol)|NFS]] server) of OpenSolaris for System z to the public.<ref>{{cite web |url=http://mainframe.typepad.com/blog/2008/10/opensolaris-for.html |first=Timothy |last=Sipples |title=OpenSolaris for System z Now Available |date=2008-10-16 |accessdate=2008-10-16}}</ref> OpenSolaris for System z has a project page at OpenSolaris.org.<ref>{{cite web |url=http://www.opensolaris.org/os/project/systemz/ |title=OpenSolaris Project: Systemz |accessdate=2008-10-17}}</ref> OpenSolaris for System z is available for download at no charge, and is governed by the same [[open source]] license terms as OpenSolaris for other platforms. All source code is available; there are no OCO (object code only) modules.
The port uses [[z/Architecture]] 64-bit addressing and therefore requires an [[IBM System z]] [[mainframe computers|mainframe]]. Because the port depends on recently defined z/Architecture processor instructions, it requires a [[System z9]] or later mainframe model and will not run on older machines. It also will not run on the release version of [[Hercules emulator|Hercules]] mainframe emulator, the needed changes are included in the SVN version 5470 of Hercules. It also requires the [[paravirtualization]] features provided by [[z/VM]]; it will not run on "bare metal" or in a logical partition ([[LPAR]]) without the z/VM hypervisor at Version 5.3 level or later. Also, because OpenSolaris uses a new network DIAGNOSE instruction, PTF VM64466 or VM64471 must be applied to z/VM to provide support for that instruction.<ref>{{cite web |url=http://
