NCR Corp. (Dayton, Ohio)

NCR was once a leading manufacturer of mid-range computing systems. Its 7500 model was an advanced design for 1978. It had a relatively sophisticated operating system in NCR-DOS and offered an 80-column display.

The Decision Mate series met with moderate success. NCR eventually renamed the Decision Mate V as the NCR Personal Computer. The company soon switched to producing PC-compatible systems with the PC4. NCR followed the PC4 with the PC XT-compatible PC6 and PC AT compatible PC8 in 1985.
