Stanford Extended ASCII is a modified version of ASCII 1963. It was in use at the AI lab (and possibly elsewhere). The Data Disc and III displays used this character set. It formed the basis for the RFC 698 "TELNET Extended ASCII Option", MIT Knight TV system, CADR, and SUPDUP character sets.
This table shows where the character sets differ. (Knight TV and Lispm are identical to SUPDUP.)
