> At least that is what I remember from the era of 8-bit home computers - like Commodore 64 and Amstrad CPC - way before the 80386. It was also common for micro computers to have RGB monitors as well. In fact the Amstrad CPC example you give specifically shipped with either a green or colour monitor and the DIN cable you'd connect from the CPC is actually a pre-VGA RGB cable. The BBC Micro also used RGB as well (with the same DIN layout at the CPC -- though Amstrad were inspired by the BBC Micro so it shouldn't come as a huge surprise the connections are the same). You're right that Commodore were often hooked up via RF but those computers did also support RGB albeit not every owner invested in a monitor. The only 8 bit micros I can think of which only supported RF was Sinclair machines (eg ZX Spectrum) but those were intentionally cheap devices aimed at the bottom of the market.
