{| class="wikitable"
! Component !! Specification
|-
| CPU || 65C02 (CMOS variant of the MOS 6502) running at ≈ 1.023 MHz. The 65C02 was used across late IIe revisions for improved instruction set and reliability.
|-
| System bus || 8-bit data bus, 16-bit address bus (64 KB addressable per bank); bank switching used for Extended RAM.
|-
| RAM || 64 KB onboard + 64 KB on the factory Extended 80-Column Card (128 KB standard). Expandable further with third-party RAM cards (many collectors report 1 MB+ via aftermarket cards).
|-
| ROM || Typically 16 KB system ROMs on early IIe families; later Platinum/production revisions used combined/expanded ROM images (~32 KB total) to consolidate Applesoft/Monitor/80-column routines.
|-
| Video || NTSC composite (RCA) and RF outputs on domestic units; PAL variants for international production. Native modes: 40×24 text (40 columns), 80×24 text (80-column card), Low-res (40×48, 16 colours), Hi-res (280×192, 6 colours), Double Hi-Res (560×192, up to 16 colours via banked memory — requires 128 KB).
|-
| Sound || Single bit speaker, software-driven toggling; third-party sound cards (e.g., Mockingboard family) provided multi-voice audio.
|-
| Storage || Disk II (5.25″) common; UniDisk 3.5″ supported with controller; third-party hard disk controllers and Apple ProFile support via expansion. Cassette I/O retained for legacy use.
|-
| Expansion || Seven standard Apple II Bus slots (50-pin) plus the Auxiliary slot (60-pin) used by 80-column/extended memory hardware; many external cards available (serial, parallel, disk controllers, Z-80 CP/M card, network cards, memory expansions).
|-
| I/O & connectors || Composite video out, RF modulator, cassette in/out, game I/O header (joystick/paddle), numeric keypad connector (internal via factory keyboard on many Platinum units), DE-9 joystick on later boards/variants; serial/printer via expansion cards.
|-
| Keyboard || Full-size built-in keyboard; Platinum revisions frequently include an integrated numeric keypad and IIGS-style key legends (Command/Option), plus relocated Reset and power LED. Some regional "hybrid" Platinum IIe used original IIe keyboard layout without numeric keypad.
|-
| Dimensions & weight || 48 × 38 × 11 cm; ~5.4 kg (typical Apple IIe family dimensions/weight).
|-
| Typical model numbers || A2S2128 (US Platinum with numeric keypad), A2S2128C (Canada), A2S2128X (International), A2S2064 (European "hybrid" Platinum using older case mold).
