The system equates definition should be based on the original definitions and the Atari Profi Book. In cases where there are conflicting definitions for OS A/B (Atari 400/800) and OS C (Atari 800 XL), the Atari XL equate shall be used. And optional Atari 800 version can be optionally provided separately. For every equates also the standard description from the Atari Profi Book shall be added.
