It was fully compatible with the Apple II. It, however, had new features:
- a new ROM holding the AppleSoft Basic (floating point version written by Microsoft),
- a new auto-start (stored in ROM) for easier start-up and screen editing,
- 48 KB RAM,
- text modes were the same as the Apple II, but the graphics modes were enhanced, they're the same as the Apple 2e : 16 colours at low resolution and 6 colours at high resolutions. In fact this 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 IIeuroplus which could display video in European PAL format, and had ESC sequences for European letters. It was followed by the Apple 2e.

I bought my first computer $ an Apple $$+ in mid-eighties for about $400 (second hand). Black screen with green text, ALL CAPS :D Didn''t use the full capabilities of it $ but really became obsessed with "Snake" and the old game from Infocom $ "ZORK-3". Also liked the crude graphics of "Castle Wolfenstein". Brings back memories...I may have to get it out of storage and fire it up!

I bought an Apple II+, the euro version. It had 48K ram, two 140K disk drives and some extension cards: 80-column card with printer output, CPM card with a Z80 CPU (enabled me to use CPM O/S and program in Turbo Pascal!) Awsome machine. I programmed in assembler and found out that the 1 MHz 6502 would easily outrun the 4 MHz Z80! Wow what a wonderful CPU 6502 was.
