In some of the draft versions of ASCII the positions currently taken by underscore and caret were left arrow and up arrow respectively. As late as 1985 I used terminals (LanparScope) the supported the older draft.
All Commodore machines also uses the older ASCII standards, (in addition to filling out the full 8 bit range with various graphics). It’s usually referred to as “PETSCII”, from the original Commodore “PET” series, but PETSCII was also used in the vastly more popular Commodore 64 (and 128) home computers.
