<!-- to be mentioned [[USASCII-8]] -->
Eventually, as 8-, [[16-bit computing|16-]], and [[32-bit computing|32-bit]] (and later [[64-bit computing|64-bit]]) computers began to replace [[12-bit computing|12-]], [[18-bit computing|18-]], and [[36-bit computing|36-bit]] computers as the norm, it became common to use an 8-bit byte to store each character in memory, providing an opportunity for extended, 8-bit relatives of ASCII. In most cases these developed as true extensions of ASCII, leaving the original character-mapping intact, but adding additional character definitions after the first 128 (i.e., 7-bit) characters. ASCII itself remained a seven-bit code: the term "extended ASCII" has no official status.
For some countries, 8-bit extensions of ASCII were developed that included support for characters used in local languages; for example, [[ISCII]] for India and [[VISCII]] for Vietnam. [[Kaypro]] [[CP/M]] computers used the "upper" 128 characters for the Greek alphabet.{{citation needed|date=November 2023}}
