Extended ASCII Table

There are well over 200 different "extended" (8 bit) versions of the ASCII character set.

Extended ASCII provides 256 characters, the extended part making up characters 128-255.
Various extended versions have been developed for different purposes such as to support proprietary technology, different alphabets, or simply to draw nice boxes on the screen.

Below is the CP437 (Code Page 437) version which was present on the original IBM PC, based on characters used in Wang word processing machines.

This particular set of extended ASCII characters are sometimes referred to as ALT Codes because in Windows it is possible to hold down the ALT key and type the 3 digit ASCII code on the number pad to output a character not physically present on the keyboard.
