Honestly? Probably the device you already have, via emulation - old Palm hardware is definitely a rabbit hole, and it's worth dipping a toe before you dive in.
CloudpilotEmu [1] is a free emulator that runs in a web browser, and works very well on smartphones. It's what I use when I feel the need to scratch my Space Trader itch, and it's definitely where I'd recommend starting. There are any number of repositories still active of old software you can run with it, and I'm sure folks will chime in with their favorites to give you some places to start.
