This is an exceptionally rare, original edition of the Apple Programmer's Aid #1 (Part No. 030-0013-01), published by Apple Computer, Inc. This manual serves as the definitive guide for the Apple Utility Programs stored on the Programmer's Aid ROM chip (specifically for the Apple II and II Plus). It covers essential low-level programming tools, including the Renumber/Append utility, the Music Note program, and the Hi-Res Graphics subroutines. This manual is a foundational text for anyone studying the development of Integer BASIC and the evolution of the Apple II system monitor.

Manufacturer: Apple Computer, Inc.

Condition: New/Old Stock (Still sealed in original protective factory shrink-wrap; see pictures for true condition)

Model Number: 030-0013-01

Extra Notes: Finding early "Red Book" era Apple documentation still in its original factory seal is incredibly uncommon. This manual was designed to accompany the optional ROM chip that plugged into the Apple II motherboard, providing advanced users with the tools needed to push the hardware's limits. Because it remains sealed, the internal registration card and any potential "Apple Computer" stickers are likely preserved inside, making this a museum-grade specimen for elite Apple collectors.
