These are IBM’s first computers: IBM 5100 (1975) and IBM 5110 (1978).
The 5100 had 256 characters but half of the characters were just underscored versions of the other half. It used IBM’s mega obscure EBCD encoding instead of ASCII. IBM 5110 dropped most of the underscored characters, which made room for semi-graphic characters. Encoding was changed to the slightly less obscure EBCDIC, and there were 14 localized character sets with 12 characters each.
Character set photos from Voidstar, where there are also more details about the character sets.

Article in Popular Electronics 1974 to build an ASCII-compatible keyboard for 40 USD. Posted on archive.org as Apple documentation, so this was presumably used for the Apple I.

Archeological maps in ASCII from 1975. A good way of visualizing spatial and other information simultaneously, and obviously a forerunner to both text adventure maps and modern cartography, as noted here.
Also check the typewriter maps, fat font for text-mode infovis & the virus map.
