TOS 2.06 EPROM set


Set of two drop-in replacement EPROM chips for Atari STE line, programmed with original Atari TOS 2.06. Not compatible with STF(M) machines. Different language options available.

SKU: TOS206 Category:


Replacement TOS memory chips, programmed with original Atari TOS 2.06 ROM image. This is latest version ever released by Atari Corp. for Atari 520STE, 1040STE and Mega STE. Available in English, French, Czech, Swedish and Spanish. Please choose your desired language variant in selection box above.

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
I suggest you to replace PCB wire links / zero-ohm resistors with pinheaders, so that you gain a flexibility to switch between different EPROM types. Once these jumpers are set accordingly, simply replace your current ROM chips with new EPROMs. Note your new chips are labeled (HI) and (LO), make sure you insert them in corresponding sockets, labeled same way.
