Hi,

Today I've been working on ColourPET again. I was re-arranging the output bits to match C128 VDC colours, when I noticed the background colours are all wrong. So I looked on the PET schematics, and for the video ram Commodore mixed up the ordering of the bits (probably to make routing easier) going from the 2114 chips to the latch. DOH! I've read the schematics a hundred times and missed this. Anyway, off to re-wire again ;-)

Steve
