| | UTR #26: Compatibility Encoding Scheme for UTF-16: 8-Bit (CESU-8) |
 | | It should be noted that this bit distribution table is identical to that of UTF-8 except that the input value is a sequence of UTF-16 code units, not a scalar value, and that a four-byte transformation is disallowed. | | | The bit pattern 1111xxxx is illegal in any CESU-8 byte, effectively prohibiting the occurrence of UTF-8 four-byte surrogates in CESU-8. | | | The resulting data stream is encoded into an eight-bit form using the bit distribution table in definition 2.2. |

| | UTF-8, the object of this memo, uses all bits of an octet, but has the quality of preserving the full US-ASCII range: US-ASCII characters are encoded in one octet having the normal US- ASCII value, and any octet with such a value can only stand for an US-ASCII character, and nothing else. | | | The remaining bit(s) of that octet contain bits from the value of the character to be encoded. | | | UTF-7 has the quality of encoding the full BMP repertoire using only octets with the high-order bit clear (7 bit US-ASCII values, [US-ASCII]), and is thus deemed a mail-safe encoding ([RFC2152]). |

| | Applied Color Theory - Field Test of 8-bit vs. 16-bit |
| | Again, here it is not 16 bit editing that matters but the fact that, even in 16 bit mode, Photoshop's selections are 8 bit alpha channels. | | | I don1t consider edits on an 8 bit file to lose data due to 3rounding errors2 but that1s semantics and not worth getting into. | | | You can make a high bit mask feathered by feathering a hard selection (loaded off a reg bit file) in high bit and then pull a linear curve in the mask to make it white...but I have not tested if this high bit created mask is better than one in 8 bit alpha. |

| | More Than a Bit of a Difference: 8-bit Versus 16-bit - Photo Tips @ Earthbound Light |
| | Thus, both are off by a factor or three (8 bits per channel times 3 channels = 24 bits total, and 16x3 = 48 bits). | | | If an image is a bit underexposed and lacking in contrast, it may only use values between 0 and 199 perhaps (200 out of the possible 256 values). | | | Instead of counting the number of bits per channel, they are named after the total number of bits in all three channels together. |

| | 8-bit clean - Wikipedia, the free encyclopedia |
| | "Eight-bit clean" is a term which describes a computer system that deals correctly with extended character sets which (unlike ASCII) use all eight bits of a byte, such as the ISO 8859 series and the UTF-8 encoding of Unicode. | | | This leaves the top bit of each byte free for use as a parity bit or some kind of flag bit. | | | Up to the early 1990s, which is much longer than when it became popular, many programs and communications systems used to assume that all characters have codes in the range 0 to 127. |

| | Atari 8-bit family |
| | Atari built a series of 8-bit home computers based on the MOS Technologies 6502 CPU, starting in 1979. | | | The 800 was rather complex and expensive to build, while the 400 didn't compete technically with some of the newer machines appearing in the early 1980s, so in 1982 Atari started the "Sweet 16" project to address these issues. | | | Atari also produced a number of other tape drives for use in eastern Europe where they continued to sell into the late 1980s due to their low cost. |

| | Atari 8-Bit Computers: Frequently Asked Questions |
| | While the 8-bit Atari computers in their heyday were technically quite comparable if not superior in the worlds of home and business personal computing, they also live up to the name "Atari" with a huge library of video games which were often outstanding for their time. | | | The 5200 SuperSystem is actually nearly identical to the 8-bit computers internally, yet cartridges for the 5200 and the 8-bit computers cannot be exchanged, primarly due to the physically different cartridge ports. | | | It is limited to a maximum of 2 computers and thus 2 or 6 players, meaning one free port per XL/XE computer and 3 free ports per 400/800 computer. |

| | The next phase of Atari computers included the continuation of the 8-bit line with the 65XE and 130XE as well as the XE Game System, which was based on the 65XE. | | | Of course, the Atari 5200 SuperSystem and 8-bit computer share the same hardware, so many of the games are identical. | | | These computers feature unparalleled sound and graphics and introduced the world to something called "player-missile graphics." This concept of graphics would later become recognized as the term, "sprite." The original 800 had 16K of RAM that was later expanded to 48K. |
