Space Quest: The Lost Chapter

Online version of Space Quest: The Lost Chapter for PC DOS. Space Quest: The Lost Chapter is a fan-made text parser adventure created by Vaughn Gosine under the alias Vonster D Monster and released as freeware for PC DOS in 2001. It runs on Sierra's original AGI interpreter, so it looks and plays like the first two Space Quest games. The story fills the gap between Space Quest II and III: Roger Wilco's escape pod crashes on a swampy planet, and the way off leads through an underwater city to the alien ship Vercotron. The game uses almost everything the AGI engine has room for.

IBM PC with MS-DOS

Online emulated version of Space Quest: The Lost Chapter was originally developed for the IBM PC and compatible computers, with MS DOS - Microsoft Disk Operating System. It is an OS for x86-based personal computers mostly developed by Microsoft and released in 1981 as PC DOS 1.0.
MS-DOS was targeted at Intel 8086 processors running on computer hardware using floppy disks to store and access not only the operating system, but application software and user data as well. Progressive version releases delivered support for other mass storage media in ever greater sizes and formats, along with added feature support for newer processors and rapidly evolving computer architectures. Ultimately, it was the key product in Microsoft's development from a programming language company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI.
