Rare complete set of seven original Digital Research CP/M manuals from 1976–1979 — the foundational operating system that paved the way for MS-DOS and early microcomputers.

These are authentic first-edition Digital Research publications from the era of Gary Kildall, not reprints or photocopies. All are clean, complete, and in excellent condition for their age.

💬 Collector’s Note:

If you appreciate the roots of personal computing, this set is a time capsule from the dawn of the microcomputer revolution. These manuals are straight from Digital Research, the company founded by Gary Kildall, whose CP/M operating system powered countless early systems before MS-DOS. The crisp pages, bold vintage colors, and classic DRI design make this a standout piece for any vintage computing shelf, museum display, or enthusiast’s collection. Finding a complete, clean set like this is truly rare.
