Multics + AS400: DPS8M on IBM PASE for i (OS/400)

Finally, you can run dozens of multiprocessing Multics instances along side your mission-critical IBM AIX (PASE) and IBM i (OS/400) workloads on IBM Power Systems hardware!

This is the virtualization solution your IT department has been waiting for… well, perhaps it isn’t — but supporting this platform is a great demonstration of both the capabilities of the IBM PASE for i (Portable Application Solutions Environment) runtime for enabling OSS on IBM i, and the excellent compatibility and portability of the DPS8M simulator software.
