The effects were cool (including the ability to change the bitrate of the terminal, made me understand why ed would make sense even aside from the other resource constraints, even `cat` takes ages at low speeds). There were also a bunch of included sounds like hardware boots (relay clicks, fan ramp up, etc…)
But the neatest thing is is that IIRC its “DRM scheme” was that the display would slowly degrade if you didn’t have a paid license. You could also degauss it (though I don’t think it would fix the degradation, you had to reboot for that). Obviously if you liked the degradation effect you could keep it even with a paid license.
