ITT 2020 personal computer, manufactured by ITT for the European market under license from Apple Computer as the first licensed Apple II clone. The top of the case features an "ITT 2020" plate, with a smaller "Apple System" emblem below the keyboard. On the bottom is an ITT Consumer Products (UK) Ltd. label, hand-labeled with serial no. "10307." Inside are an Apple Disk II Interface Card and a generic clone of the Microsoft Z80 SoftCard.
The principal difference between the ITT 2020 and the Apple II was that its color video signal output conformed to the European PAL standard, rather than the American NTSC standard, meaning that it could be viewed on a standard European monitor or TV set; a European user of the Apple II would have needed to import an NTSC monitor. The ITT 2020 also increased the horizontal resolution of the output, a necessary consequence of the higher frequency of the PAL color subcarrier.
