HeadRoom is a DOS context switching and multitasking memory manager produced by Helix Software Company in the late 1980s and early 1990s. HeadRoom managed multiple Terminate and Stay Resident programs and was the first TSR manager to allow sharing of address space and interrupts among TSRs in DOS. HeadRoom v1.0 was released in September 1988. In October 1989, Helix Software released HeadRoom v2.0 which included support for Microsoft Windows and LIM EMS v4.0. Starting in March 1990, this version of HeadRoom was bundled with AST Research RAMpage, RAMpage Plus and SixPack memory expansion boards.
