- For those in possession of an Atari STE it is necessary to have a soldering iron and perform some simple operations in order to complete the upgrade in your system
In order to upgrade your system with these EPROM chips, you must configure W102, W103 and W104 as follows:
W102: 1-2
W103: 2-3
W104: 1-2

- For those in possession of an Atari Mega STE it is not necessary to perform any particular operation, except to replace the ROMs in place of those already present. 

Do pay attention to the direction of the chips by checking the position of the notch.
Placing the chips the wrong way may damage them !

Any modification on the motherboard is the sole responsibility of the buyer.

In case of problem, we decline all responsibility if you make an assembly error, a chip direction error, or poorly done soldering.

​

Open your Atari and check your motherboard before purchasing any TOS ROM set.

​

Although the fitting of these is a simple task, please be sure that you know what you're doing before fitting.

Some motherboards indicate which Rom is which (Hi and Lo), if your board does not have this information, but only Uxx, Uxx… then look for the information online. Or search for pictures that will show you the correct placement.
