How- ever, s/he wasn't patient enough, as the listing of events that was displayed there did not reach far enough into the future to cover AppleFest. The new Apple Direct will soon be out, and at the bottom, in full living blue and white, it states that AppleFest will be showing in San Francisco on 9/22-9/24. You can all breathe a sigh of relief now... 2) There was a question concerning what the error numbers meant from the Apple IIGS diagnostics. I didn't know what they meant at the time, but Matt Deatherage was kind enough to forward this to me so that it could be posted: Apple IIGS: System Diagnostic Errors This article last reviewed: 10 November 1988 Here's the currently available, though incomplete, list, with explanations, of error codes generated by the Apple IIGS when running system diagnostics for the Apple II Family (V1.0B1). Apple IIGS error codes have the form AABBCCDD.
