Inside a Classic

The Mac Classic is an amazing piece of Apple engineering. Here’s what’s inside

Cathode ray tube

A 9-inch 512x342 black and white screen. Many PCs still had green and black displays back then.

Expansion slot

The SE was the first Mac to use the Processor Direct Slot (PDS). This one contains a DaynaPORT network card.

Drive caddy

1.4MB floppy disk drive, plus an optional 20MB or 40MB SCSI hard disk.

Motherboard

Hidden underneath everything else is the motherboard, with a 16MHz 68030 Motorola CPU and 1MB of RAM (expandable to 128MB).

Ports

Two ADB ports for keyboard and mouse, Two DIN-8 serial ports, plus ports for external floppy and SCSI drives.

Power supply

The dangerous highvoltage capacitors for the screen are exposed. Leave the Mac switched off overnight before removing the case.
