This allowed me to have 8 colours, then 8 colours I could use for palette based animations via the VDU19 call. It was an effect that myself (And Henley of TYB fame) used to great effect to produce scrolling landscapes and Tron like grids in the demos we wrote for the BBC. | |

I myself preferred the "amber" color which was produced by monitors without the circuit than the "brown" color produced by those with it. | |

Flashing is purely internal to the video circuitry and doesn't need additional pins | |
