Apple IIe Platinum

Apple IIe Platinum Reference Hub

The Apple IIe Platinum (1987) kept the IIe spirit while bundling key upgrades into a cleaner package. This page provides technical documentation that may be useful when you want to run software, troubleshoot hardware, or write code to emulate classic Apple II behavior. Feel free to check out my latest open-source emulation software on github.

Model year: 1987 CPU: 65C02 @ ~1MHz RAM: 128KB (typical) Built-in keypad + 80 columns

Useful Documentation

Filter by what you are trying to do. Start with owner docs for setup, then move to technical references for deeper work.

Fast Path: first hour with a Platinum

  1. Read startup + disk operation chapters in the Owner's Guide.
  2. Keep the Technical Reference Manual open for memory map and slot behavior lookups.
  3. If coding, pair Beneath Apple ProDOS with monitor commands from the reference manual.
  4. Before hardware changes, check service docs for board revisions and connector pinouts.
