Note 1: Thanks to information supplied by David Empson several early System
Failure Code messages (e.g. "File map destroyed") are now considered to be
suspect as to accuracy. Yes, some kind of error has occurred; but, as David
points out, the messages seem to have been incorrectly copied from Mac with no
particular regard to relevance on the IIgs:
For example, all the errors referring to "Can't load a package" make no
sense - the IIgs doesn't have any such thing as a package (but early Macintosh
system software does). Here is another big clue: error $30 is allegedly "Please
insert disk (File Manager alert)". There is no such thing as the "File Manager"
on the IIgs, but there is on the Mac."-- David Empson
Basically, it appears that the faulty messages function as defaults (place
holders) when more accurate third-party messages are not supplied. The suspect
messages may appear; so, they remain in this listing; but, now they are marked.
Error messages marked ** indicate a System Failure message considered to be
suspect.
Note 2: Error messages marked **** indicate that a more detailed discussion is
available in Question 004.
