SIMH is a highly portable, multi-system emulator. This is the repository for the bjornhell/simh Docker image that contains pre-compiled versions of all the emulators supported by SIMH version 3.9-0.
The image is a good starting point if you want to create runnable versions of old hardware, but be aware that you won't be able to run anything with this image alone: It only contains the SIMH simulator, but none of the operating systems supported by the emulated hardware.
Emulators present in this image:
