# Symbols for Legacy Computing Supplement

Symbols for Legacy Computing Supplement is a Unicode block containing additional graphic characters that were used for various home computers from the 1970s and 1980s, extending the set of characters provided by the Symbols for Legacy Computing block.
It includes characters from Amstrad CPC, Apple 8-bit, Kaypro CP/M, Mattel Aquarius, Ohio Scientific, Robotron KC, Sharp MZ computers, HP terminals, and TRS-80. It includes a set of semigraphics in the form of 230 "octant" characters, large images split into four "characters", and the "large type" characters used for building large text characters.
