From: Rudolf Harras on 7 Jan 2010 07:36 I wonder for what reason Commodore used a boarder in all their Computers like the VC20, C64/128? I don't know any other computers having this and it also wasn't so usual that time, was it? It makes the picture smaller and it seems to be difficult to have some sprites there since I don't know any game where the boarder is useful. On the other hand I'm really so used to it that an OS without "Boarder" does not seem to be complete for me. :)

You never saw an Atari 400, 800, or Radio Shack Color Computer? They all had borders (I don't know if they had "boarders" or not!) Tom Lake

Weird. Ok, so it was usual that time. But why? Well of course I ment "border", not "boarder".

It varies widely between old CRT sets. That's just one reason -- there are probably additional technical reasons, though it is possible to code around the border thing and put sprites and other things in the borders. -- -Brandon http://www.brandonstaggs.com/c64.html |
