RE: 264 Series and their chips

I asked Dave Diorio and his recollection was the same as mine which is the
"5"s were processors and the "3"s were graphics, ancillary,  etc.  Which
doesn’t make sense in light of the 8563 etc.  <sigh> Time was when I
remember this stuff like it was only 15 years ago.

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.

hell.

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?
