A-ONE Prototype Board (with Breadboard)
Plug-in prototyping + permanent hardware expansion for A-ONE
Take your Apple-1 replica experience beyond software and into real hardware.
The A-ONE Prototype Board is designed as a seamless expansion module for the A-ONE ecosystem, giving you a complete prototyping environment for custom electronics.
It integrates directly with the A-ONE Standard and Extended boards and turns your system into a flexible hardware development platform.
Two Powerful Features in One Module
At its core, the Prototype Board combines two prototyping approaches:
-
Integrated breadboard — fast, solderless experimentation
Ideal for ICs, resistors, sensors, and interface logic
-
Solderable prototyping area — plated-through matrix board
Convert successful experiments into permanent hardware
Prototype quickly. Validate your idea.
Then commit your final design — without changing platforms.
Direct A-ONE Bus Access
Connected via the 44-pin A-ONE edge connector, the Prototype Board exposes the full system bus.
This allows you to:
-
Develop new peripherals
-
Expand memory
-
Test communication interfaces
-
Experiment with bus logic
-
Build custom hardware features
You are working directly at the system level — exactly how early home computer pioneers designed their expansions.
