What symptoms does a dodgy CIA-chip give on an A1200? Does it affect the floppy-connector in any way?
Depends on which of the 2 CIAs is flakey.
Floppy disk problems could be either chip,
U8 send all the control signals(motor, disk selects,head step + direction etc)
U7 reads it's status(write protect,disk change, ready etc.)
Other things that the CIAs affect...
Keyboard, joystick buttons+mouse button problems could be U7
Serial port is U8
Parallel port , data lines controlled by U7, control lines by U8
Keep in mind that faults elsewhere in the Amiga could cause the same problems, such as broken traces, shorts or faulty components between the CIA and the floppy,parallel and serial ports.
