Replica 1 plus Users Manual Figure 6: Video connector Next you need to attach a keyboard. You have two choices for keyboards; PS/2 PC style keyboard or an ASCII keyboard. To use the PS/2 style keyboard locate the PS/2 port on the back edge of the replica 1 and plug your keyboard into that port (see figure 7). Figure 7: PS/2 keyboard port If you are using an Apple 2 or 2+ ASCII keyboard, locate the ASCII keyboard port near the replica 1 logo on the board and plug your 16pin dip cable into the board. Note that pin 1 is next to the ‘A’ on the ASCII KEYBOARD label. Please note, you will need to supply your own -12V power for Apple II keyboards. Figure 8:
ASCII keyboard port Now you are ready to test your replica 1 plus. Make sure your TV or monitor is turned on and flip the switch on the replica 1 up. The red LED below the switch should light up and a screen of garbage should appear. If you do not see the random garbage screen, or the LED is not lit, turn the replica 1 off and recheck your work. Press RESET on the board and your replica will respond with a backslash “ \ ” and the cursor will drop to the next line. The cursor is a blinking ‘ @ ’ symbol just like the original Apple 1 computer. You are now in the Woz monitor and ready to use your replica 1 ten.
If you are using the PS/2 style keyboard you will notice that the caps lock is already on by default for you. The apple 1 only understands uppercase characters so does the replica 1. © Briel Computers 2014 page 11
