As Apple was struggling with manufacturing capacity because of the booming demand of their device, Apple II was sold in Europe before the genuine Apple II hit the European market. Whereas Apple II worked with 8 bits, the ITT 2020 worked with 9. The ITT 2020 was designed to produce a PAL video signal for the European market, as against an NTSC for the domestic US market.
