How to Build your own Apple 1

Build the iconic Apple computer from scratch

There's no doubt the Apple 1 is an iconic computer. We decided to re-create this classic machine with the help of an unassembled kit. Find out how we got on.


Early computers were designed for functionality, not aesthetics. The Apple 1 did not come with a case; hobbyists instead designed their own, including carving wooden cases or retrofitting briefcases.

The Replica 1 is similarly utilitarian, so there's a power LED right on the board to indicate the on/off state. Here I'm holding the LED, which has two leads that slide into the appropriate holes, in my left hand; the longer lead is the positive end and is inserted where the + symbol indicates.

From left to right are a composite video output, a serial port, a DC power input, and the on/off switch. Not all of these parts were included in the original Apple 1; the RS232 serial port, for example, allows the Replica 1 to interface with and download data from modern computers.
