The RAM refresh is extremely simple, and removing it from the videochip would just have costed money. On each raster line, the video chip reads 5 addresses from $3FFF-$3F00. The refresh counter counts downwards, and it is a function of $D012 (i.e. it resets at raster lines $100 and $00). Marko - This message was sent through the cbm-hackers mailing list.
