ECS scandoubler for A500 / A2000

A homebrew scandoubler project. It is bug free, supports DPMS energy saving and PAL / NTSC screenmodes. It fits into A500 and A2000 perfectly.

The logic is realized with a Xilinx XC95144XL CPLD. The video DAC is a ADV101 from Analog Devices.

On the pictures below You can see how the rev. 3 is fitting in an Amiga 500.

And the rev 4. in Amiga 2000. Needless to say, both prototypes are working properly.
