Here's a simple simulation of the 1980s experience: https://virtualconsoles.com/online-emulators/c64/ If your kid is like most kids, they might spend 20s on this before they get back to their Youtube/TikTok/Instagram/Roblox fix. Or maybe a few hours at best if there's a very enthusiastic adult sitting next to them explaining everything. But they'll probably be back at their regular internet distraction as soon as the adult is gone.
For a decent recreation of the 1980s experience, you'd need to shut the kids off from the internet for some extended period. But even that is only an approximation, if they have any contact with other kids.
