# 68k Mac OS

IDA is the most powerful disassembler for Max OS 8 and Mac OS 9 PEF files.

The Motorola 68K family of processors is huge and very widely used. A few sample parts: MC68000, MC68010, MC68020, MC68030, MC68040, MC68330, MC68882, MC68851, MC68020EX, MC68302 Integrated Communication Processor, MC68306 68K/ColdFire, MC68331 68K/ColdFire, MC68332 68K/ColdFire, MC68336 68K/ColdFire, MC68340 68K/ColdFire, MC68360 Integrated Communication Processor, MC68F375 68K/ColdFire, MC68376 68K/ColdFire, etc.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.hex-rays.com/8.4/user-guide/disassembler/disassembly-gallery/68k-mac-os.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
