At one time, nintendo had to take all NES back because of problems with overheating!
Everyone had an NES in the 80s.

The most popular problem was that the cartridges got dusty and you had to BLOW inside the NES and cartridge to make it work again.

NES roced.

8 binary numbers (ie. 10110101, which is equal to the decimal 181) that form 1 bit. During the late 1970's up through the mid-late 1980's, most commercial CPU's could only count 8-bit numbers, ranging from 0-255.

Somehow, people only tend to think of video games when refering to 8-bit things, which it completely innacurate. Many computer systems, as well as video games, were concidered "8-bit."

8-bit processors were eventually replaced by more powerful and faster 16-bit CPU's such as IBM's 8080 line and Motorola's 68000.
Computers: Atari x00 series, Commodore series (PET 16, C-64, C-128, etc.), Apple series, and other similar systems that used the 6502, 6800, or Z-80 processors and their varients.

Game systems: Atari 2600 and 5200, Nintendo Entertainment System (NES), Nintendo's Gameboy, Sega Genesis, Colecovision, etc.

nes was a system that took everything and put it back to place, without the original nintendo you wouldn't have your "PS2's" and "Xbox's". At one point all of nintendos systems were being taken back because of every single problem you had to face due to such a fucken piece of shit at least segas system didn't have catridge defiency but this square piece of ingenious technology couldn't last a day without constant blowing and the constant clicking of the on and off button.
the nintendo never got old it just fell apart.
