* Palette: 16 registers, 12‑bit RGB (4‑4‑4). Raster tricks permit more onscreen colors.
* Scrolling and BLiTTER: hardware fine horizontal/vertical scroll; BLiTTER accelerates block moves, line fills, and masked ops (PLCC‑68, or integrated in later GST MCU).<ref>{{cite web|url=https://mikrosk.github.io/doitarchive/doit_st/080104.htm|title=DOIT_ST: BLiTTER|publisher=DOIT_ST|access-date=2025-08-12}}</ref>
* Sprites: none (implemented in software with BLiTTER or CPU).
* Outputs: 13‑pin DIN RGB/mono; optional RF modulator on “W/MOD” assemblies for TV display; SCART compatible with passive cable (resistor recommendations vary by model).<ref>{{cite web|url=https://info-coach.fr/atari/hardware/interfaces.php|title=Atari Video cables and SCART mapping|publisher=Info‑Coach.fr|access-date=2025-08-12}}</ref>
