Remove the cover from the computer by releasing the four screws on the bottom of the unit.
Step #2Carefully lift the keyboard to reveal the flex cable connecting it to the main PCB.
Gently pull upwards at the base of the flex cable to part it from its socket.
Be very careful with this cable, bending it can destroy it.
If your 65XE still has the RF shield installed, you will need to remove it
to access the PCB.
To remove the top RF shield you must straighten a number of metal tabs around the edge of the shield using needlenose pliars.
After unbending these tabs, the top shield should lift off.
Step #4After removing the RF shield, locate the OS ROM on the motherboard. Its location is marked on the photograph. If your OS ROM is soldered in, continue to step 5 to replace it with a socket. If the OS ROM is socketed, skip ahead to step 8.
Step #6Carefully desolder the OS ROM. Be very careful when removing the ROM after desoldering. The traces on the 130XE motherboard are VERY FRAGILE and will delaminate easily from excess heat or force. If the ROM does not lift out easily, re-check your desoldering work before proceeding. In the empty place where the OS ROM was located, install and solder in place the 28-pin DIP socket included in your installation kit. The completed work is shown here, with a socket ready to accept the Warp+ OS upgrade.
Step #8Carefully remove the OS ROM from its socket and place it in the anti-static container your upgrade came in. If you ever want to restore your computer to it factory configuration, you will need this ROM.
Remove the Warp+ OS upgrade board from its package and insert the board into the OS ROM socket.
The photo on the right shows the correct orientation of the OS board in the Atari. Do not insert the board backwards or it will be damaged. Damaged boards will not be replaced.
DO NOT APPLY EXCESSIVE FORCE INSERTING THE BOARD.
If you encounter too much resistance inserting the board into the socket, check the alignment of the pins in the socket and make sure it is correct.
Press straight down on portion of the board over the OS ROM socket to insert it. Do not insert the board at an angle or one side at the time, as this will bend or break the gold pins.
Once the board is inserted, look underneath it to verify all the gold pins are in the socket. If any are hanging over the edges then remove the board and re-insert into the socket correctly.
Step #10A wire set for 3 solder connections is included with your OS upgrade. One connector has 2 wires, the other has 1 wire. Using the connector with 2 wires, solder one wire end to connection point 'R' and the other to connection point 'S' as shown in the photos. Using the connector with 1 wire, solder it to connection point 'D' shown in the photos. Connect the WHITE wire to this location. Connection point 'D' is the right side of R87 in the 65XE.
Connect the RED wire to this location.
Connection point 'S' is the right-most resistor in the row just above the flex-cable connector for the keyboard. This is the top of R135 on the 65XE.
See the large photo above for its location. The photo to the right is a close-up of this location
Be careful not to bridge the connection between any of these pads.
Connect the BLACK wire to this location. If your kit has two black wires, cut off one of the black wires near the plug, only one is required. (It does not matter which one you remove)
Once you have soldered the 3 required connections, you must plug them into the header on the OS Upgrade board.
Orient the connector so that the RED WIRE is on the side of the white asterisk (*) printed on the circuit board. The black wire(s) will be in the center, and the white wire on the right.
Attach the power and monitor connections to the Atari and turn it on.
The system should start normally (possibly with a dark-blue screen), and you should reach BASIC or SELF-TEST.
If the system does not function normally, check all connections.
Reassemble system and re-test. On some models you may have to omit the RF shield or cut a hole in it.
Hold SELECT down on the keyboard while powering up the Atari to reach the OS Selection Menu.
The descriptions you entered when building your OS will appear on screen. Simply select a new OS using the keyboard and the system will reboot using that OS.
Every time you power on the Atari it will use the OS you selected. To change the OS again, just hold down SELECT while turning on the computer.
You may also hold SELECT+OPTION down on the keyboard while powering up to reach the APE Remote Control software.
