86Box

86Box (formerly PCem-X, PCem Experimental or PCem Unofficial) is a hypervisor and IBM PC system emulator based on PCem that specializes in running old operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus. It is developed by the SoftHistory collective lead by Battler.
