The author is all over the place, but it is still interesting video to watch. I didn’t know that in the 80’s BBC was powerful enough to tender its own line of PCs, and then force UK government to finance half of their price.
Also it’s fascinating how they had mixed resolution: part of the screen was “high-res”, but black-and-white, whie the lower part of the screen had 8 colors, but was rendered in lower resolution.
