Transcribing The Source Of The First DOS For The IBM PC
Hackaday • • general
Key Points:
- Tim Paterson, creator of 86-DOS and MS-DOS, has provided printed source listings of early MS-DOS development, including the 86-DOS 1.00 kernel and utilities like CHKDSK.
- These printouts feature handwritten notes, making the transcription into working source code a challenging process, but much of it has been completed and is available on GitHub.
- The transcribed code includes versions such as 86-DOS 1.00, MS-DOS 1.25, and PC-DOS 1.00-dev, all requiring the Seattle Computer Products assembler to compile.
- Original scans of the listings are accessible on Archive.org, and the project page README links to blog posts with additional technical insights.
- The project invites community participation for further transcription and testing of the recovered source code.
