The Apple II Plus was the second model in the Apple II computer family. One major improvement is that Applesoft BASIC was stored in ROM, while Integer BASIC had to be loaded in from a disk. It was also expandable to 64KB of RAM, 16KB more than its predecessor! (No, that’s not a typo, we’re talking KILOBYTES). Laughable today, but back then programmers often designed quality software with every byte accounted for.
