Having owned only one IIgs, I didn't realize that Apple Keyboard II I received was not the original keyboard. The ESC key position has been driving me a little bonkers. Well, I got my 2nd IIgs delivered yesterday, and with it, the true original keyboard. All is good in the world again!
Just had to share. I have a lot to learn...
You should test the mouse button for reliability especially when it is kept pressed down while running gs/os.
Care you expand on that? Are you talking about original keyboard or Kbd II issues? I've tried keeping the button pressed and I do not see any issues.
Expanded!
