| ABC80 | 1978 | | 1K | 40×24 Mono | Semi: 78×72 Mono | (39×24) | LC, BG | — | | One of the first systems with serial attributes like Ceefax and Prestel systems, needed the first character of a line for switching to graphics mode, thus the horizontal resolution is 78, not 80 |
| Apple II | 1977 | | 18K | 40×24 Mono/6 colors | Full: 280×192 Mono/6 colors Semi: 40×48 15 colors | 40×48, 140×192 | | | | First known system with 4 line "caption" and software scaling and rotation |

| Interact Home Computer | 1979 | | 2184 bytes | 17×12 4 colors | Semi: 112×78 4 colors | 112×78 | Characters were drawn on a 112×78 pixel graphics screen which means that each character was 6×6 pixels, including blank space between the characters, which led to very blocky characters, which simply didn't allow for distinct lower case characters. | In theory, the "graphics" screen text was drawn on could be the text-mode semigraphics screen for a more standard (for the time) 56×26 or 56×39 high-resolution text mode, though in practice this real text mode was apparently never used (if it even could be). | 4 of 8 | |
| Kaypro II series | 1982 | | 2 KB | 80×24 Mono, on 9-inch built in CRT | Semi: Presumably 160×72 Mono | (80×24) | LC, BG | No | - | |

| Osborne 1, Osborne Executive and Osborne Vixen | 1981, 1982, 1984 | | 4K | 52×24 Mono on 5-inch CRT, later 80×24 on 7-inch CRT | "Full": Presumably limited 416×192 Mono, later limited 640×192 using its pseudo graphic characters set | (52×24, later 80×24) | LC, SG | | Uses virtual screen to make up for limitations of original 5-inch CRT, a feature presumably not dropped from later models in order to achieve full backward compatibility |
| Panasonic JR-200 | 1983 | | 2K+2K | 32×24 8 colors | "Full": 256×192 8 colors Semi: 64×48 8 colors | 32×24 | LC, BG | | unique semi-graphic pixel color attribute scheme made that each of the 64×48 semi-graphic "pixels" (consisting of a quarter of an 8×8 pixel character space) could have its own independent color, these semi-graphics could be combined with predefined characters, or programmable characters, each of which could also have an independent foreground and b |

| LINK 480Z and Research Machines 380Z | 1982 | | 2K | 40×25 or 80×25 Mono | A separate independent video display generator board could be added that did support high resolution graphics of 640×192×1, 320×192×2 or 160×96×4 bits per pixel | LC | | n of 16 with Hires expansion board; 16 out of 256 logical intensities with composite interface, 16 logical colors with TTL RGB interface | |
