Comments
The Apple II Plus replaced the Apple II. It included the Applesoft BASIC programming language in ROM. This Microsoft-authored dialect of BASIC which was previously available as an upgrade, supported floating-point arithmetic (though it ran at a noticably slower speed than Steve Wozniak's Integer BASIC) and became the standard BASIC dialect on Apple II computers. The Apple II Plus had a total of 48K RAM, expandable to 64K by means of the language card, an expansion card that could be installed in the computer's slot 0. The machine's 6502 microprocessor could support a maximum of 64K of memory.
