I decided to build my own replica from scratch, including the PCB design, as it's a very nice occasion to learn about electronics.

As a programmer, I sometimes feel frustrated not to know more about this... ; )

### Power Transformers

I'm using the original schematics and original Apple-1 photos in order to identify the components and build the PCB.
|
||||
The original [**Apple-1 Operation Manual**](Documentation/Apple-1 Operation Manual.pdf) is included in the repository.

When the components are still available for purchase, links are provided ([Mouser Electronics](http://www.mouser.com/)).
|
||||
For vintage components, valid alternatives may be provided. In such a case, I try to find components that look the same as the original.
|
||||
|
||||
### Rectifiers
|
||||
Unfortunately, I haven't been able to find alternative for all components, so your best option to find those parts is on sites like [eBay](http://www.ebay.com/). Note that rare/vintage components can be expensive.

Schematics

Here's a schematic of motherboard layout, with all components.
|
||||
Note that the components' size is not respected, and their position is not always totally correct, but it's still better than looking at original pictures for quick component identification:
