A 40/80 Character Expansion For The VIC-20
An often discussed disadvantage of the VIC-20 was the number of columns of the screen. The length of a screenline was just 22 characters. This could not prevent the VIC computer from being a success in the hobby world, but it made (semi)professional applications impossible.
Computer World has designed an expansion to make the VIC suitable for professional applications, e.g., accounting and word processing, especially when using the Brother 8300 daisy wheel printer/typewriter, adapted to operate with the VIC-20.
