"PCem (an acronym for Personal Computer emulator) is an open-source, low-level PC emulator developed for Windows and Linux by Sarah Walker. It focuses on PC hardware from the 1980’s and 1990’s. A variety of operating systems can be installed in the emulator, which can then be used to launch programs."1
