The Apple II+ was the successor of the Apple II.
It was fully compatible with the Apple II, however it had some new features: a new ROM containing the AppleSoft Basic (floating point version written by Microsoft), a new auto-start (store in ROM) for easier start-up and screen editing, 48 KB RAM, text modes were the same as the Apple II, but the graphic modes were enhanced. They’re the same as the Apple IIe: 16 colours with low resolution and 6 colours with high resolution. In fact the 6-colour mode was also available on the Apple II since revision 1 of the motherboard.
The Apple II+ was sold in Europe as the Apple II Euro plus, which could display video in European PAL format, and had ESC sequences for European letters. It was followed by the Apple IIe.
