86box is a little different than dosbox in that it fully emulates the hardware. Performance might still be an issue in your case, though. I have an emulated voodoo banshee system for playing old games and it works great for my use case of supporting old glide games. My thinking being if it can support glide emulation that it would be able to support anything from the dos era. I could be wrong though.
That’s more like a tank destroyer top. It looks like a hetzer to me
