IBSYS is a discontinued tape-based operating system that IBM supplied with its IBM 709, IBM 7090 and IBM 7094 computers, and a significantly different, though similar operating system provided with IBM 7040 and IBM 7044 computers. IBSYS was based on FORTRAN Monitor System (FMS) and (more likely) Bell Labs' "BESYS" rather than the SHARE Operating System.
