VM/SP

The only info I can find is in a couple of glossy brochures from IBM. One is about the 9370, the other about the 3090 series. Respectively, IBM Virtual Machine/System Product (VM/SP) This is a multi-user, multi-processing operating system for interactive processing. It provides productivity tools for commercial and engineering/scientific environments, decision support and program development. With its connectivity enhancements, this system is particularly suited for remote sites that have little or no programming staff. and Simple end-user interaction with VM The VM/XA Systems Facility and the VM/SP High Performance Option both provide a virtual machine environment. Together with the Conversational Monitor System (CMS), they permit each end-user to access the IBM 3090 system independently, with the perception that he or she is the sole user. Communicating with the IBM 3090 via VM/CMS, Vector Vacility users can develop, test and execute vectorised applications online, using a comprehensive range of IBM Assembler and FORTRAN compilers, libraries and productivity tools. VM also provides guest System Control Program (SCP) support, not only for other IBM SCPs but also for IX/370, IBM's implementation of UNIX. Sorry I can't be of further help. Philip.
