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.

A 40-pin expansion connector (far right) was used by earlier models of the Replica 1, but with the addition of a 44-pin, Apple-1-compatible expansion port in this, the third edition, the connector is no longer necessary for expansion.

Two new parts not found in the Apple-1 will be installed nearby: a connector for an ATX power supply and the aforementioned 44-pin expansion port, similar to those found in the Apple II.

The Replica 1 uses two distinct power regulators that are not interchangeable and must be installed with the correct orientation.

I identify the two unique regulators correctly and put them in the right spots - but rotated 180 degrees from their proper orientation. Thus the parts need to be de-soldered from the board. This is beyond me, so Replica 1 creator Vince Briel and Paul Zaleski grab a soldering iron and a 'solder sucker' to fix my mistake while I watch helplessly.
