A solid effort from the folks at NCR. The Century 300 was a full-scale mainframe system that debuted in September of 1970. Utilizing monolothic IC's, it had 67 standard instructions and two independent execution units with overlap. Disc, drum and tape were available. Note quite a few cutting-edge features for the time.
This video replaces a rough kinescope I uploaded in 2015. This replacement is a frame-by-frame scan released in 2K resolution, with image noise reduction. The 16mm print had shifted heavily to red; while far from perfect, I was able to pull some color back out.
