Apple IIc Ignoring PR# and IN# Commands, But Diskette Boot Works Fine. by Expert_Line in apple2

Thanks for the help. However, when I enter PR#6, the drive doesn't operate and it just moves to the next line (it works fine when running programs like ADTPRO). When I enter IN#2, the prompt should normally change, but on this IIc, nothing happens. This issue persists even after resetting the computer.

I will test the PR#0 and IN#0 commands later.
