Notes:

Soviet/Russian chip names use Cyrillic alphabet. These names are presented in the table in three variations:

  • using Latin alphabet. Russian characters are replaced by similarly sounding english characters.
  • using Cyrillic alphabet (Windows 1251 encoding). Some browsers may incorrectly display this name.
  • using Cyrillic alphabet (every Cyrillic character is presented by an image). This should work in any browser, but it useless for "cut and paste" and "search" operations
