The PDP-8 is readily [[emulator|emulated]], as its instruction set is much simpler than modern architectures. Enthusiasts have created entire PDP-8s using single [[field-programmable gate array|FPGA]] devices.

Several software simulations of a PDP-8 are available on the Internet, as well as [[open-source hardware]] re-implementations. The best of these correctly execute DEC's operating systems and diagnostic software. The software simulations often simulate late-model PDP-8s with all possible peripherals. Even these use only a tiny fraction of the capacity of a modern personal computer.
