Apple II Plus

The Apple II Plus made Microsoft-derived Applesoft BASIC the standard firmware and was normally supplied with 48KB of RAM. It retained the original Apple II's case, colour graphics, sound and eight-slot expansion architecture.

Floating-point BASIC and mature Disk II storage made the computer better suited to education, business and packaged software. International Europlus and J-Plus variants adapted video standards and keyboards for markets outside North America.

Notable Features

• Applesoft BASIC replaced Integer BASIC in ROM and added floating-point arithmetic.
• 48KB became the normal memory configuration for commercial software.
• Eight expansion slots preserved compatibility with the rapidly growing Apple II ecosystem.

Historical Significance

• The model on which the Apple II became a mature international software platform.
• Strong sales carried Apple from the pioneering 1977 design into the early 1980s.

Collector’s Notes

• Apple II, II Plus, Europlus and J-Plus machines can appear similar but use different ROMs and regional hardware.
• Period Disk II drives and language-card expansions define many complete systems.
