In 1982 DEC released the DECmate II, a desktop built on the aging PDP‑8 architecture. The machine combined two built‑in floppy drives, a monitor, keyboard and printer into a turnkey office system. With a Z80 or 8086 processor card it could run CP/M or a MS‑DOS, and users could add extra drives, a hard disk or a graphics card, making it attractive for small businesses.

DEC’s original PDP‑8 debuted in 1965 at a list price of $18,500, offering 4 K words of magnetic core memory and a 667 kHz clock. Its 12‑bit, 1.5 µs cycle time made it the first affordable minicomputer, selling nearly 1,500 units and spawning the 8/E, which later fell below $5,000. The architecture’s simplicity encouraged clones and later micro‑processor adaptations.

Because the DECmate II retained PDP‑8‑compatible instruction set, hobbyists can replace its floppy drives with solid‑state storage and tap its video output for modern experiments. The project demonstrates that even a 12‑bit machine can host contemporary tools, reminding engineers that legacy hardware still offers a sandbox for low‑level programming and hardware interfacing. The restored DECmate II runs reliably today.
