Atari 400 Upgrade
In your December 1982, Issue 31, someone inquired about the flaws in the operating system of the 400/800 computers. I have an Atari 400 with the old operating system. Is there any way for me to get the new OS (revision B)? or is there any way to upgrade the existing ROM?

No officially supported OS upgrade is offered by Atari, but you might contact your local Atari Service Representative. The ROMs are not on a removable board in your 400, so it is even harder to upgrade.
