Symbols for Legacy Computing is a Unicode block containing graphic characters that were used for various home computers from the 1970s and 1980s and in teletext broadcasting standards. It includes characters from the Amstrad CPC, MSX, Mattel Aquarius, RISC OS, MouseText, Atari ST, TRS-80 Color Computer, Oric, Texas Instruments TI-99/4A, TRS-80, Minitel, Teletext, ATASCII, PETSCII, ZX80, and ZX81 character sets. Semigraphics characters are also included in the form of new block-shaped characters, line-drawing characters, and 60 "sextant" characters (semigraphic character made up of six smaller blocks).[3][4] Additional characters were added to this block in Unicode 16.0 as well.

A supplemental block (Symbols for Legacy Computing Supplement) was added with Unicode 16.0.
