This show is Atari ST
Atari ST was a good computer in the eighties and early nineties.
It had a relatively good, multi-tasking OS, an interesting (though limited) sound chip, hundreds of colors, nice resolutions, capable graphics chips, good Motorola 68000 CPU, and it even looked good.
It had good games, neat demos, music utilities (trackers and such), and it was popular with musicians because of its inbuilt MIDI connector (so you could plug in synthesizers and easily program them and compose for them).
However, when you compose music with its limited, three-channel sound chip, you start missing composing for the C64's three-channel SID chip instead, because the SID has a filter, four waveforms, mixed waveforms, ring-modulation, synchronization, and the filter is pretty amazingly flexible to produce all kinds of neat and quirky sounds and effects easily, together with the other effects.
Heck, some really good, classic songs have been composed for it, that get your energy pumping and blood flowing and the good ol' euphoria mode going.
When you play an Atari ST game, you may enjoy the experience, but then it starts hitting you - the Amiga version of this game is just so much better, the scrolling is smoother, the picture area is bigger, the sprites have more animation, the music is much better, the sound effects are actually great, instead of bleeps and bloops, and the Amiga version even has more colors, and nice 'Copper-colorslides' that the Atari can't mimic. Often all you get is a plain one-color background, where Amiga has a neat, smooth Copper-colorslide.
So basically, whatever you do with the Atari ST (besides MIDI stuff, maybe), you start missing some other platform, chip or way of doing that same thing. You do graphics? You start missing Amiga's Deluxe Paint and Brilliance. You watch demos? Well, Amiga demos are just unbeatable. You play some colorful game, like Shadow of the Beast? Well, just look up some youtube comparison videos.
Watching Orville makes you miss watching TOS and TNG instead, maybe even Voyager and Deep Space Nine. Orville is a good show, but I enjoy Data way more than Isaac (that no one knows how to spell the name of), I enjoy Worf more than the weird, pale gay copy of him, and I can't stand all that sighing that Seth does after 90% of the things he says.
This show is definitely Atari ST, and not an Amiga or SID.
