XL Upgrade For Atari 800?
I would like to know if it would be possible to build a new ROM Operating System board that would duplicate the XL operating system on my Atari 800. Is it true that Atari will offer a ROM Revision C?
If you had access to the ROMs used in an XL computer, you could in theory replace the ROMs on your OS board. You still would not be able to take advantage of many XL features. Bank-switched memory requires more than a new operating system, since there have been some hardware changes in the XL computer series. We know of no plans to offer an upgrade to existing Atari 400 and 800 owners, but some third-party companies market add-on boards with 64K RAM and limited compatibility with the Atari XL computers.
