Atari Forum — 2600, 8-bit, and ST | 6502ish
Atari Forum
Three different eras, one logo.
Atari is three different stories with the same logo. The 2600 (technically the VCS) more or less created the console games industry in 1977. The 8-bit computer line that started with the 400 and 800 in 1979 held its own against the C64 for a decade. And the 16-bit ST, launched in 1985 with built-in MIDI, ended up being the computer that made the 1980s dance music scene possible.
Three tracks, three cultures:
- The 2600 / VCS crowd is mostly game-focused, with a strong homebrew catalog and the AtariAge community anchoring most of it.
- The 8-bit computer people (400, 800, XL, XE) argue about whether theirs was actually better than the C64. It often was on paper — the POKEY chip, the player-missile graphics, the better hardware sprites — but the C64 won the software library war.
- The ST camp is its own thing: music producers, demo coders, GEM/TOS programmers, and the Falcon 030 holdouts.
Things worth knowing across the Atari family:
- Atari's engineering documentation was unusually detailed. Jay Miner (before he went to Amiga) and the 8-bit team published schematics and chip-level specs that are still valuable.
- The hardware tends to survive better than Commodore equivalents. The PSUs are less aggressive about killing the motherboard when they fail.
- Commercial Atari died repeatedly — twice, depending on how you count — and every time the community carried on without a corporate home.
Where to go from here:
- Atari ST — music, graphics, 68000 computing
- Atari 8-bit and 2600 hubs are planned; for now the discussion is in the general forums.

Frequently Asked Questions
Which Atari should I start with?
Depends what you want. For games and the broadest catalog, the 2600/VCS. For 8-bit home computing, the 400/800/XE/XL line. For 16-bit work — especially music — the ST. These are three different cultures, not a continuum.
Do Atari 8-bit and Atari ST share software?
No. The 8-bit line runs MOS 6502; the ST runs Motorola 68000. Completely different instruction sets and completely different hardware. Atari shared the brand but not the architecture.
What's the difference between Atari 400/800 and XL/XE?
Same core hardware — same CPU, same custom chips (ANTIC, CTIA/GTIA, POKEY) — packaged in different cases with different keyboards. The XL/XE introduced slight ROM updates and OS improvements but everything runs across the family with rare exceptions.
Is Atari still around?
The name is, but the original engineering organizations died repeatedly through the 1990s. Current Atari is a licensing company that periodically ships retro-branded products. The community keeps the original machines going entirely independently.
