86Box is described as 'Hypervisor and IBM PC system emulator 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' and is a Virtualization tool in the network & admin category. There are more than 10 alternatives to 86Box for a variety of platforms, including Mac, Windows, Linux, BSD and iPad apps. The best 86Box alternative is VirtualBox, which is both free and Open Source. Other great apps like 86Box are DOSBox, UTM, DOSBox-X and DOSBox Staging.
Here you can find the original version of David Hedley's 8086 PC emulator, and my "improved" version. This will emulate a basic PC with a VGA text-only display quite well; there is a reasonable amount of software that will work with no problems.
