VSPC

Virtual Storage Personal Computing (VSPC) was a service offered by IBM in the late 1970s and early 1980s^[1]. From a data terminal, users could run both interactive processes and batch jobs on remote computing hardware (located in IBM service centres) to which they were connected e.g. by telephone lines using modems. Among the programming languages offered were VSPC variants of BASIC, FORTRAN, APL and PL/1. VSPC became obsolete following the invention of the Personal Computer as computing power became available to the individual user locally.
