Draw ATASCII Table
Print a reference table of Atari ATASCII codes 0 to 255. Runs entirely in your browser, so your data never leaves your device.
Output
The result appears here as you type.
How to use Draw ATASCII Table
- 1. Open the tool. Open the page and the full ATASCII reference table prints immediately, since it needs no input to generate.
- 2. Read the reference table. The table lists every code from 0 to 255 alongside its decimal value, hex value and the character or graphics symbol Atari's ATASCII set assigns to it.
- 3. Copy the table. Copy the reference chart and keep it on hand whenever you need to look up what an ATASCII byte represents.
When to use Draw ATASCII Table
Draw ATASCII Table prints the full character set used by Atari 8-bit computers, covering every code from 0 to 255 along with its decimal and hex values and the graphics or text character it represents. ATASCII reorders and adds symbols compared to standard ASCII, so a proper reference table beats guessing.
- Reading text from an Atari 8-bit disk image. You extracted a file from an Atari 400/800 or XL/XE disk image and it is encoded in ATASCII rather than ASCII. The reference table lets you manually translate specific bytes you're unsure about.
- Restoring an old Atari BASIC listing. A vintage Atari BASIC program stored on cassette or disk uses ATASCII graphics characters for its display formatting. Checking the table clarifies what each special byte was meant to draw on screen.
- Building an Atari emulator or converter. You're writing a tool that converts ATASCII text to modern Unicode and need an authoritative mapping to verify against. The generated table serves as a quick reference while testing your conversion code.
- Researching retro computing character sets. You're writing about or comparing 8-bit era character encodings across different home computer platforms. Generating the ATASCII table gives you the exact codes for that comparison.
