No, that's not correct. The II+ was a II with Applesoft BASIC instead of Woz's Integer BASIC, and the ability to automatically boot from disk at power on. That's it.

Lowercase and 80 columns were available from third-party vendors for both the II and the II+.

Worth pointing out (for those interested) that Applesoft BASIC provided floating point support, and was provided by Microsoft.

BASIC and the monitor were stored on ROM chips on the motherboard. The II and II+ were basically the same computer with a different set of BASIC ROM chips installed.

Edit: It is actually possible to have both sets of ROM chips installed if you use a Firmware card. Very handy!

Huh. I got my II+ with the 80-column card installed. I guess I just assumed that was standard. Being more than 40 yrs ago, I could be misremembering.

It was probably a Videx Videoterm:

It was common for Apple resellers at the time to sell them with third-party add-ons.
