Atari Upgrade Update
We have recently heard from several factory authorized Atari service center representatives who tell us that there is an inexpensive (under $30) upgrade for the 10K ROM operating system. The original operating system of the 400/800 had a number of minor errors (bugs), and the Revision B operating system corrected these problems. This is the first time to our knowledge that Atari has offered this upgrade. To check which operating system you have, enter: PRINT PEEK(58383). If you get a 56, you may want to visit your nearest service center and get the upgrade (a value of 0 returned means you already have Revision B).
