Personal computer, 1979, ITT. The ITT 2020 is an Apple II built under licence for the European market by ITT, with a PAL video output and a slightly changed high-resolution mode of 360 x 192 pixels to suit the European television standard. It was distributed in the United Kingdom by Microsense and in the Benelux by Bell Telephone. It runs most Apple II software and takes Apple expansion cards, and it was one of the first ways to buy an Apple II-class machine in Europe.
