Max Headroom is somewhat special, since it's a crossover of digital and video. The later has always been signaled by glitches and artifacts (as in color, unstable vertical and/or horizontal hold, overly expressed scanlines, lately also by exaggerated cushion distortion, etc).

Supporting the signalling, https://news.ycombinator.com/item?id=23833111 was definitely a product of the VCR era.
See also the expressed scanlines in the "faked" 80's of the first video in https://news.ycombinator.com/item?id=24398456 .
As for exaggerated curvature, surely we've all run across https://github.com/Swordfish90/cool-retro-term by now?
hard to achieve as a practical effect, but still cheaper than digital.
