Replica 1 TE Users Manual Chapter 3: Unpacking and Setting up system. Before you begin setting up your replica 1 computer, make sure you have plenty of table space. Do not power up the unit while touching any part of the circuit board and contact Briel computers if you are unsure about any part of the setup process. You will need the following items to get your replica 1 up and running: 1. The replica 1 system board. 2. ATX power supply or 7-9V DC wall brick supply positive center. 3. Keyboard, a PC PS/2 or an Apple II/II plus (not //e or //gs). 4. A TV with composite video in, or a composite computer monitor. 5. A video cable to attach to the TV from the replica 1.
Place or mount the replica 1 board so that it is secured. Make sure no metal objects can touch the circuit board or damage could result. Next you need to choose what type of power supply you are going to use. There are three ways you can power your replica 1 TE. ATX power supplies are the most commonly used power supplies in today’s computers. You need to use an ATX power supply if you are planning on using the Apple II ASCII keyboard because -12V power is required. If you only intend on using the ps/2 style keyboard you only need a 7-9V wall brick style power supply.
While the replica 1 shows 7V on the board, it is best to use something around 8-9V 1000mA (1.0A) if adding on an add-on board. You may need to find a heat sink for the 7805 voltage regulator to keep it cool under that much voltage drop. Figure 5: DC wall brick connector (Use 7-9V positive center connection power supply) CAUTION: DO NOT ATTACH BOTH A WALL WART POWER SUPPLY AND AN ATX AT THE SAME TIME TO YOUR REPLICA 1. DOING SO COULD DAMAGE YOUR REPLICA 1. © Briel Computers 2007 page 10
