If your wanting to play around with Open VMS abit you can get a Free Shell at Deathrow its a Cluster of Three Nodes.
"The Deathrow Cluster" is a couple of computers acting as one large computer. The cluster currently consists of DEC Alphas (64 bit), and VAXen (32 bit - Some uVAX hardware, some emulated) running the OpenVMS operating system. The idea of the cluster is to promote the OpenVMS operating system and give people a chance to play with it. People are welcome to test the security features of the cluster, port non-commerical code and learn the basic in-and-outs of the OpenVMS operating system. The cluster supports many programming languages, including: BASIC, C/C++, Fortran, Cobol, ADA, Bliss, Macro32/64, DCL scripting, PL/I, Java, and Pascal.
The cluster is available for general public use, as long it's not for commercial purposes. The cluster uses the OpenVMS Hobbyist licensing, hence the reason we cannot allow commerical usage of the cluster. Commercial usage would be violate our license agreement as OpenVMS hobbyist, and we cannot let that happen.
