That was a great episode.

Four years before teaming up with Nintendo with the Switch, Nvidia released the Shield Portable, an Android-based handheld.

Do we remember this? "The revolution will not be televised."

Not only do I remember it. Not omly did the controller mold become a cheap 3rd party controller for Switch. The commercial alone turned anyone off.

Not only do I remember it, I own one. In the Kickstarter-exclusive brown color with my username etched in no less.

Also probably the reason why it didn't come to my mind immediately.

Microvision; the first handheld console to use interchangeable cartridges, released all the way back in 1979.

This badboy had a 16x16 monochrome screen, the processor was on the game cart rather than in the console, and carried a whopping 64 bytes of RAM.

It was discontinued in 1981 after just two years on the market; according to the former head of Nintendo R&D1, it inspired the Gameboy.

The Halycon. 1980s console that used Laserdiscs. The games were similar to Dragon's Lair. QTE based FMV games. It's oneof the rarest consoles in the world. Some units exist but the system never officially released. Only a handful of games exist and the price ranged from $1800-2500 of the very few sold unofficially in a small domestic store.

This console had a 32bit AMD 386SX CPU @16MHZ. - 2MB System Ram + 640Kb Video Ram + 128Kb Sprite Ram.
Pretty ahead of it's time in retrospect.- Could even do 3D graphics, unfortunately due to the lack of sales we never saw the hardware truly taken advantage of.

Cool stuff; capability wise how did it compare to systems like the Jaguar, PS2, Saturn?

It's 3D graphics capabilities were pretty limited compared to a purpose-built 3D console like the Saturn or the PSOne.

As such, best comparison would be the Neo Geo CD, which came out a year later and was somewhat more powerful, and the 32X upgrade for Megadrive/Genesis. Neo Geo CD could do some basic 3D rendering like the later FX chips of the SNES but was way more advanced when it came to 2D rendering, while the 32X is slightly more powerful in 3D and many more colors (11bit vs 8 bit) but hasn't quite the same 2D possibilities.

It's actually most comparable to a standard low-end PC at the time (486 we becoming prominent at the time, and the first Pentium wasn't far off anymore), but with a GPU that has been enhanced to be more aimed at console games (no PC GPU came with anything like sprite RAM, for instance), otherwise it's pretty much an SVGA GPU, down to having VGA graphics options. It even comes with an internal Floppy disc drive (formatted in the PC-98 style, so not directly compatible with western PCs). As such, concept-wise but also performance-wise, it's most comparable to the Amiga CD32, which released around the same time in the west.
