Stanford Extended ASCII (SEASCII) is a derivation of the 7-bit ASCII character set developed at the Stanford Artificial Intelligence Laboratory (SAIL/SU-AI) in the early 1970s.[1] Not all symbols match ASCII.
Carnegie Mellon University, the Massachusetts Institute of Technology, and the University of Southern California also had their own modified versions of ASCII.[1]
Character set
[edit | edit source]Each character is given with a potential Unicode equivalent.
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F | |
| 0x | · | ↓ | α | β | ∧/^ | ¬ | ε | π | λ | γ | δ | ∫ | ± | ⊕ | ∞ | ∂/∇ |
| 1x | ⊂ | ⊃ | ∩ | ∪ | ∀ | ∃ | ⊗ | ↔ | _ | → | ~ | ≠ | ≤ | ≥ | ≡/≍ | ∨ |
| 2x | SP | ! | " | # | $ | % | & | ' | ( | ) | * | + | , | - | . | / |
| 3x | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | : | ; | < | = | > | ? |
| 4x | @ | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O |
| 5x | P | Q | R | S | T | U | V | W | X | Y | Z | [ | \ | ] | ↑ | ← |
