The Replica 1 is a clone of the historic Apple I of 1976. It was designed by Vince Briel in 2003. It was the first Apple 1 clone to take advantage of more modern components, enabling the clone to be produced with cheaper and more widely available components while retaining the functionality of the original. History The Replica 1 is a clone of the Apple I designed by Vince Briel with permission from the Apple I's original creator Steve Wozniak. The Replica 1 is functionally a close copy of the original but it was designed using much more modern parts on a smaller, simplified board design. The Replica 1 is designed around the same MOS Technology 6502 chip used as the core of the Apple I. Like the original, the Replica 1 utilizes simple AV in/out to connect to a television or other similar screen. It maintains most of the original's functionality, such as the lack of a "delete" key. Development Briel has described how his first prototype was developed on a (solderless) breadboards, with confirmation of success being the detection of bits corresponding to an "\" character on the output of the Peripheral Interface Adapter chip. Briel said his next prototype breadboard used a microcontroller to output to a terminal or terminal emulator program. The final prototype used a printed circuit board, and had the addition of a circuitry that implemented a 40x24 character output as per the Apple I. The only change from this prototype to the first revision a production board was the addition of a PS/2 keyboard connector. The first commercial revision of the Replica 1 came with a separate Serial I/O card, This allowed programs written on or for the Replica 1 to be stored on the hard drive of any common PC. This was needed because the Replica 1 had no other means of program storage, since cassette drives (the Apple I's storage device) are in short supply. The I/O card can also be attached to original Apple I computers. Apple had no objection to the project since Wozniak had given his approval and the design is technically Wozniak's alone since it predates the company itself. Apple had previously released all materials regarding the Apple I to the Apple I Owners Club. Original The Replica 1 was first introduced to the market between 2003, and 2005. It was always provided both as a build-it-yourself
