HP OpenVMS site http://h71000.www7.hp.com http://h71000.www7.hp.com maybe the starting point to further explore it. Also, they have a hobbyist license available for free. I haven't been involved with VMS since 2000 so not sure where such people hang out. I started my career as Fortran developer on OpenVMS for process control systems and process simulations in early 90s. OpenVMS was the choice platform for most mission critical/ life critical operations and for manufacturing process simulations then. We ran a few pair of OpenVMS nodes in cluster to operate multimillion dollar petrochemical production facility. The share-everything clustering was cool. I don't think I have seen that since. Actually OpenVMS helped me make transition from petrochemical to technology in 2000. A tech company was trying to find someone with prior experience in OpenVMS to support customers using their optical storage library management software on OpenVMS/Alpha. That's when I transitioned from controls to data storage.
