I'm now unpacking and trying to work out how to proceed with further interaction in 2020, and the one machine that keeps crossing my scope is an old Macintosh Powerbook, the first with a trackball, which has indeed been loaded up with HyperCard stacks.
Now, one thing I must add to this discussion, as someone who has had to demo these things to a modern audience, is that the person you are showing it to should always be the one doing the driving. Never try to show someone a stack - always just describe them doing it for themselves.
Stacks are delightful. Get yourself an emulator, and explore them. Its a pretty good way to get some context on your newly-gained modern chops.
