And what computer back then didn't have a border? With TVs as the main 
display device you didn't have much of a choice.

The border area on a PAL 264 is a lot smaller than on a PAL C64 so with 
some adjustments of the displays it should have been possible to 
minimize the border further and then always set border and background to 
the same color.

My main display for those old systems is a 1084 monitor, that one allows 
you to adjust all parameters. An LCD doesn't quite cut it when it comes 
to flickerfree soft scrolling and the 1084 does have an S-video input.

BTW: Do you remember why some of the 8xxx-Chips got an 85xx-Number and 
some got an 83xx?
