Both base images were provided by Tony Ingenoso
The Image-I Adapter/A always fills the screen with 1600
x 1200 pels. The 1360 x 1024 and 1024 x 768 are just windows within this.
The 640 x 480 mode is pel doubled to look like 1280 x 960.
The 9504 is specifically designed for the Image Plus market
to run at 1600 x 1280 resolution. If used in other resolutions than 1600
x 1280 the reduction in picture size is as follows:
1600 x 1280 = 370 x 296 mm
1360 x 1024 = 315 x 237 mm
1024 x 768 = 237 x 178 mm
640 x 480 = 296 x 222 mm
