Replica 1 TE Users Manual Chapter 2: Introducing the replica I TE computer The replica 1 computer was designed to give those people a chance to see what an Apple I computer looked and acted like. Most people have never seen an Apple 1 running and the replica 1 helps us see what Woz had created. The goal of the replica 1 project is to simulate the functional aspects of the Apple 1 so that all hardware and software designed for the Apple 1 can be used. Figure 3: Key component features on the replica 1 TE Not just a simple hobby board. The replica 1 contains features such Apple 1 compatible expansion slot, original replica 1 connector and your choice of ATX or wall wart power supply..
Other features include a built in serial port that intercepts the keyboard and video signals so software drivers are not required. A PS/2 keyboard port is onboard for those who don’t have ACII keyboards, and a simple On/Off switch for applying power to the replica 1. Firmware upgradeable: The new TE model (Third Edition) includes a Parallax Propeller micro-controller for the onboard I/O. The source code is open source and is included with the replica 1 on the CD and updates can be made via free software to program the Propeller from Parallax website. Programmers are welcome and encouraged to use the Briel Computers forum to announce custom developed features and improvements to the firmware.
The owner takes all responsibility for any firmware installed that is not released or approved by Briel Computers. Using untested firmware could damage the replica 1 TE. © Briel Computers 2007 page 8
