You get the message I/O ERROR (Input/Output) on your screen.
Take
the disk out of having trouble exchanging information with a peripheral
device. Most of the time, it points to a problem with a disk drive. (With 5.25-
inch drives, you get this message if the drive door isn't shut.)
Take the disk out of the disk drive and see if it's the one you thought it was. If it's not,
replace it and repeat what you were doing when you got the error message. Check to make sure
your printer and disk drive are securely plugged into the computer.
You can also get this message if your drive is connected to slot 1, 2, or 3 and you're using
the Fast system speed.
Disk II controller Switch to Normal speed or connect the drive to slot 4, 5, 6,
or 7. I/O is slowed down automatically in these slots for Disk II controller
cards so you can use software designed for earlier models of the Apple II.
You get the message SYNTAX ERROR on your screen.
This is a general-purpose error message that tells you the computer didn't
understand your last instruction. Sometimes you get this message when you
type something in lowercase letters and the application wants it in uppercase letters.
Check your typing. If you have made a mistake, retype the command. If that wasn't the problem,
try pressing Caps Lock down and typing your entry again.
You can't get to desk accessories by pressing the Apple key-Control-Esc.
Your application uses a version of ProDOS earlier than 1.2, which doesn't give
you access to desk accessories. Sometimes you get this message when you type something in
lowercase letters and the application wants it in uppercase letters.
Have your authorized Apple dealer upgrade the application to ProDOS 1.2.
The Desk Accessories menu appears unexpectedly.
You tried to access desk accessories earlier from an application that didn't let
you. The computer held on to your request and complied as soon as possible.
Choose Quit from the Desk Accessories menu. Have your authorized Apple dealer
upgrade the version of ProDOS on your application disk so you can access desk
accessories when you want to.
The application works on an Apple IIe but not on an Apple IIgs.
Fast speed might be interfering with the application.
