I recently picked up a 130xe and 1050. I had these when I was a kid back in the 80's. I have many floppy disks from that time and most of them still work.
Some may not work due to the fact my original 1050 had a Happy mod.
Anyways, one in particular contained the "Smurf Demo". Many of you may remember this animation of a 2 smurfs, one being smurfette.
I won't go into any more detail except for color. The demo still runs , but instead of several shades of Blue on the screen making up the characters and backgrounds,
There are shades of reds the darkest almost a brownish and they seem a bit pixelated. Can't remember if original was pixelated.
This seems to be the only color issue I have found so far on this computer. Other games seem to have proper color. Could this be an issue with the graphics chip only affecting a certain mode this demo uses? Could is be a corrupt file on the old disk? I have tried RF and Composite to an older Panasonic TV with the same result as well as composite to VGA conversion on a older Sony monitor and the demo is absent of any Blue. Are there any tests I can perform to rule out Atari hardware? I appreciate any suggestions.
Thank you
Mark
