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 of 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.
