actually, the fairchild f8 video game is really named the Fairchild Channel F, (the sorry part is the looking up fairchild f8, in wikipedia, which reminded me of the fairchild channel f.
I bought one approx 30 years ago in a blow out sale.(usa)...
Besides the above, there was the TRS-80. It had catridge games and was a console for the TV.

Famicom, Super Famicom - Japanese consoles I rank them as different as they had different hardware then the NES.

There also are all the 5 in 1 games out there, like the Namco Series 1, 2 and 3 of pacman, ms. pacman, etc.

Virtual Boy
The FM Towns Marty.

And how exactly does Moores Law work if the size of the chips changes? Are mobile 'Core 2's not really the same speed as their exactly-the-same-speed-rated 775 socket versions, for example?

Isn't 1.2GHz for example, the same 1.2GHz per core, whether the CPU is mobile or desktop / 775 / 771 etc sized? Ye-es, there'll be cache differences & so forth, but what I am getting at here is that Moore's Law used to be invoked to claim that it'd be impossible to ever make a 5GHz silicon chip, because you can't cram that many transistors onto that surface area without them ceasing to be operational as the different paths would leak into one another.

But that's happened, so what if there's more than one core....it's still one chip.
The Vetrex! Did anyone here ever have one of those? Kind of like an apple II I think. Cartridges, mono CRT screen (built in) with plastic inserts to make it "Colour", cabled controller... Wow!
It only took me three seconds to realise that they had actually missed quite a big and important console...

Neo Geo.

And how could they? The Neo Geo had cartridge sizes so large they could've easily competed against the sizes of entire consoles by Sega or Nintendo...
I think it's missing the Super Nintentdo, the best colsole ever made. The one that give birth to PlayStation (The SNES SoundChip ASIC, the SPC700 was made by a single man: Ken Kutaragi)
NES
SNES
TI-99/4A... It used cartirdges and surported sprites
The home version of the Neo Geo
Atari 5200
Atari Jaguar
Virtual Boy
They forgot the odyssey 2. I had one because my folks couldn't afford to get me the atari back in those days. It was fun but kinda generic when it came to games.
Nes, Snes, Sega Master System, Atari Jaguar, Sega Game Gear, Game Boy (+ colour + advance), Atari Lynx, Neo-Geo, Panasonic 3DO.

that's about all i remember off the top of my head :)
If I win, I want to improve world piece by touring Smithfield, a walkaround with the butcher. Does anypunter know the going rate for bronze salvages? Blighty sounds like an adult Dizzy World. 
Let's see...

1. Nintendo
2. Sega Master System
3. 3DO (I bought one, sadly)
4. Jaguar
5. CD-i
6. Super Nintendo (almost missed this one)

Probably missed a ton, that's all I can think of though.
I assume that mentioning the Nintendo 64 twice was a typo (a peculiar one, if you ask me), and that you meant Super Nintendo. Then add the original Nintendo. Atari Jaguar (the erstwhile "64"-bit system) is out. The 3DO (and it's countless variants) hardly counts, I suppose. You might count Apple's abortive Pippin platform, but the company that made the only production model (whose name escapes me) only punted them in Asia, I believe. Magnavox Odyssey.

That's off the top-o-the-head.
N64^2?

By the looks of it, they were shy on Nintendo's representation.

NES
Super Nintendo
3DO
Atari Jaguar

Handhelds:

Atari Lynx
TurboGrafx CD
Sega Game Gear
Game Boy
Game Boy Pocket
Game Boy Color
Game Boy Micro
Game Boy Advance + SP
Nintendo DS + Lite
That one weird Japanese one that had a lot of RPGs on it
Sega Nomad (handheld Genesis FTW)
Nokia N-Gage
Microsoft Bob (it held your hand, at least)
...all of the handheld consoles. the far to numerous gameboy incarnations, the game gear, the lynx, neo geo pocket, there was even a sega handheld that played genesis cartridges but i forget the name...

oh and also, HOW COULD THEY FORGET THE NES?????
well i see that the nintindo and super nintindo are missing .

porta-consoles
game boy, game boy color, atari lynx,
turbo express. ok i am head hurts, thats the early ones i am sure some one will pick up hte torch
JVC/SEGA Wondermega, which is a Megadrive and MegaCD in one rather flashy expensive unit with extraordinary build quality!

fairchild f8. had a cool 3 axis joystick... (twist is the third)
Wasn't there a console by Fujitsu, the FM Towns? And the Philips CD-i.

A classic: TRS-80

I miss playing Poltergeist the most.
The Bandai WonderSwan (color), the bestest portable ever
... the dodgily named WonderSwan?

I'm sure it had a dodgily named brother or sister too, but I'm not going to look it up, as per the rules.
That piece of crap went so fast from the store shelf to the bin that it made dragonflies dizzy.
And nobody else has quoted it either.
The Vetrex! Did anyone here ever have one of those? Kind of like an apple II I think. Cartridges, mono CRT screen (built in) with plastic inserts to make it "Colour", cabled controller... Wow!
I used to love mine, playing games with the wrong coloured screens added a whole new dimension to escaping homework.
What about the Philips G7000?
an Amstrad GS too?
Nice too see some people finally remembered the CD32, Before that was the CDTV and before that the C64GS.
the Dick Smith Wizard. Hopefully only sold in Australia & NZ
We should count the Neo geo pocket!
just go to the MAME site and read through the supported systems list...?!
They missed the amiga cd 32

nice little console that
how about a Sega megadrive or the Commodore CD32 (or their previous 1 which i cant remember the name of lol)
The Amiga CD32! What a fool I was for buying that, and then to compound matters I replaced it with a 3DO...
Everyone had forgotten about the Amiga CD32, which was a A1200-based console.

How about the Atari Jaguar or the original Nintendo instead of 2 Nintendo 64s, Doh!
Where's pong? Or even the Neo-Geo?
original Nintendo and the Gameboy

The hammer is really POWERFUL. If you use it to swat a fly and it lands a hit, that little flying critter is DEAD.
