  • Note : Actually both RGB's 127 (#7F) or 128 (#80) values can be used to generate the CPC palette's half tones on a true colour modern computer.

CPC6128 R,G,B signals (measured by nocash)

  • Test

  • Green

  • Red

  • Blue

The pictures are showing the RGB outputs on a CPC6128 with classic (non-cost-down) mainboard (measured between the monitor connector and R126,R128,R130). Each divider is 100mV in height.

The CPC is connected to the RGB input of a Philips Philetta TV Set (this is important for the test, as the monitor does pull-down the signals, without monitor connected both "max" and "half" signals are around 4.0V, with monitor connected they drop to circa 1.0V and 0.5V, as seen in the pictures).

  • The Toshiba PASOPIA 7 is known to feature the same 3-values RGB palette as the Amstrad CPC, its video mdoes are different than Amstrad CPC's ones though.
