6 ROM Rainbow TOS 1.04 for Atari 520ST, 1040ST, Mega 2, Mega 4, Stacy, in the following languages available:
American (American), German (German), French (French), English (English), Spanish (Spanish), Swedish (Swedish), Dutch (Dutch), Czech (Czech).
Select the language you want from the drop-down menu.
This listing refers to the six ROMs named: HI0, HI1, HI2, LO0, LO1, LO2 (see photo to understand where they should be inserted) to be inserted on your Atari 520ST, 1040ST, Mega 2, Mega 4, Stacy. Check on your Atari if you have the 6 sockets to accommodate this version of the TOS.
A mini how-to for installing the ROMs in English (or Italian if the order comes from Italy) is included.
No particular skills required. No welding required.
They simply need to be inserted into the motherboard sockets (located under the power supply), paying attention to the orientation of the ROM.
I recommend once again to pay attention to the direction of the ROMs (see notch on the side of the ROM itself) and to respect the position HI0, HI1, HI2 and LO0, LO1, LO2 (High and Low). Take as a point of reference the ROMs that you have already inserted into your Atari or in the photo here.
For any information I am at your complete disposal.
