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 130XE 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. Connection point 'D' is the left side of R87 in the 130XE. Connect the WHITE wire to this point.
Connection point 'R' is the top pad of R40 in the 130XE. Connect the RED wire to this point.
Connection point 'S' is the center pad in a group of three, just to the right of the ANTIC chip on the right side of the board.
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 point. If your wiring kit includes
two black wires, cut one black wire off near the connector (it does not matter
which one). Only one black wire is required.
Another photo showing points 'S' and 'D' with wires sucessfully attached.
Disregard wire colors, they may be different in your kit.
Once you have soldered the 3 required connections, you must plug them into the header on the OS Upgrade board.
Align the header so that the RED wire is nearest the asterisk (*) printed on the circuit board.
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 made need to omit the RF shield during re-assembly or make a hole in it to accomodate the module.
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.
