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. "13352." Included is an ITT 2020 floppy disk drive and three operating system floppy disks, an “ITT Micro Computer System” folder with four instruction manuals and a “2020 Logic Circuit Diagram,” a “Disc Interface Board” (13 sector version), a video adapter, and an “ITT, Apple System” software cassette tape, with one side marked “Basic Test Program,” and the other “RAM Test.” In overall fine condition, with scattered marks and scuffs to the computer case.
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.
