The Apple IIe (styled as "Apple //e") is the third model in the Apple II series of personal computers produced by Apple Computer, Inc. Introduced in January 1983, it became the most popular and longest-lived Apple II variant, widely used in education, business, and the home.
🧠 Architecture and Processor
The Apple IIe is based on the MOS Technology 6502 microprocessor, running at 1.023 MHz. Later revisions (the Enhanced IIe and Platinum IIe) used the CMOS-based 65C02 CPU, which offered additional instructions and improved reliability.
Key architectural features:
- 8-bit data bus, 16-bit address bus (64 KB addressable memory space)
- Integrated keyboard with full ASCII support and four-way cursor keys
- Support for 80-column text (with included or optional 80-column card)
- Seven internal expansion slots for peripherals and upgrades
💾 Memory and Storage
The standard Apple IIe shipped with:
- 64 KB RAM on the mainboard (expandable via memory cards)
- 16 KB ROM containing Applesoft BASIC, Monitor, and system firmware
Storage options included:
- Cassette tape interface (via rear port) for basic program storage
- Disk II 5.25" floppy drive – the most common storage medium
- Optional 3.5" UniDisk drive (with controller card) for ProDOS support
- Optional hard disk (e.g., ProFile) via expansion card
The IIe could be expanded with auxiliary memory cards, enabling up to 128 KB or more for advanced applications and double hi-res graphics.
🖥️ Display and Graphics
The Apple IIe featured versatile text and graphics modes:
- Text: 40×24 characters standard; 80×24 with 80-column card
- Graphics:
- Low-res: 40×48 pixels, 16 colours
- Hi-res: 280×192 pixels, 6 colours (colour limitations per line)
- Double hi-res: 560×192 pixels, monochrome or up to 16 colours (with extended memory and Enhanced IIe)
Video output was provided via composite video (NTSC), suitable for colour or monochrome monitors and televisions.
🔊 Sound Capabilities
The Apple IIe included a simple 1-bit speaker, driven by toggling a memory-mapped address. This allowed for basic beeps and software-generated tones, but no dedicated sound chip. More advanced audio could be achieved via third-party sound cards (e.g., Mockingboard).
🎮 Input/Output and Expansion
The IIe was designed for expandability and connectivity:
- Seven internal expansion slots for disk controllers, serial/parallel cards, memory expansion, CP/M cards, and more
- Auxiliary slot (for 80-column/extended memory card)
- Game I/O socket for paddles, joysticks, and light pens
- Composite video output (NTSC)
- Cassette input/output (mini-jack)
- DE-9 joystick port (on later models)
- Keyboard with reset key and open-Apple/closed-Apple keys
The IIe supported a wide range of peripherals, including printers, modems, and networking cards.
