# Microsoft BASIC for 6502 Microprocessor - Version 1.1
|
||||||
|
|
||||||
|
## Historical Significance
|
||||||
|
|
||||||
|
This assembly language source code represents one of the most historically significant pieces of software from the early personal computer era. It is the complete source code for **Microsoft BASIC Version 1.1 for the 6502 microprocessor**, originally developed and copyrighted by Microsoft in 1976-1978.
|
||||||
|
|
||||||
|
### Why This Document is Historically Important
|
||||||
|
|
||||||
|
#### 1. Foundation of the Personal Computer Revolution
|
||||||
|
|
||||||
|
- This BASIC interpreter was the software foundation that powered many of the most influential early personal computers
|
||||||
|
- It democratized programming by making it accessible to non-technical users through a simple, English-like programming language
|
||||||
|
- Without this software, the personal computer revolution might have developed very differently
|
||||||
|
|
||||||
|
#### 2. Microsoft's Early Success
|
||||||
|
|
||||||
|
- This represents some of Microsoft's earliest and most successful software
|
||||||
|
- The licensing of this BASIC interpreter to multiple computer manufacturers was crucial to Microsoft's early business model
|
||||||
|
- It established Microsoft as a dominant force in personal computer software before MS-DOS or Windows
|
||||||
|
|
||||||
|
#### 3. Multi-Platform Compatibility
|
||||||
|
|
||||||
|
- This single codebase was designed to run on multiple different computer systems of the era
|
||||||
|
- The conditional compilation system allowed the same source code to target different hardware platforms
|
||||||
|
- This approach influenced how software would be developed for decades to come
|
||||||
|
|
||||||
|
## Supported Computer Systems
|
||||||
|
|
||||||
|
The source code includes conditional compilation support for multiple pioneering computer systems:
|
||||||
|
|
||||||
|
- **Apple II** (`REALIO=4`) - Steve Jobs and Steve Wozniak's revolutionary home computer
|
||||||
|
- **Commodore PET** (`REALIO=3`) - One of the first complete personal computers
|
||||||
|
- **Ohio Scientific (OSI)** (`REALIO=2`) - Popular among hobbyists and schools
|
||||||
|
- **MOS Technology KIM-1** (`REALIO=1`) - An influential single-board computer
|
||||||
|
- **PDP-10 Simulation** (`REALIO=0`) - For development and testing purposes
|
||||||
|
|
||||||
|
