Byte Shop Apple 1 Replica.Subject: Apple 1 Plus ReplicaThe first widely available Apple-1 reproduction was the Replica 1, created by Vince Briel in 2003. His pioneering work proved that there was strong interest in revisiting Wozniak’s legendary design,to design a replica that was not only faithful to the Apple-1 but also minimalistic, using the fewest parts possible while retaining full functionality. This philosophy became the cornerstone of theByte Shop Apple 1 Replicaproject.From Schematics to PrototypeBy studying the original Apple-1 schematics shared by Steve Wozniak with the Homebrew Computer Club. The biggest challenge was to keep the design simple, true to the spirit of the Apple-1, but still practical for modern use.
Instead of dozens of small RAM chips, a single larger SRAM module. For address decoding, a GAL chip, which replaced several individual logic chips while retaining the same functionality.
The keyboard controller was based on an ATtiny2313, making it possible to connect a modern PS/2 keyboard, while still keeping the feel of a 1970s homebrew computer.
Collaboration and InnovationPermission from Steve Wozniak himself to use the original Apple-1 ROM code – including the famous Woz Monitor and Apple BASIC. This made the A-ONE not only a hardware replica but also a true functional descendant of the Apple-1.
