Yes, one - RPI have 700MIPS and various hardware accelerators so you can waste resources and do bit banging where Amiga have around 0.6 - 0.8MIPS and bit-banging need to be smart and limited to maximum.
You can use various ports in Amiga as GPIO - joystick/mouse ports are bidirectional, serial and parallel are bidirectional, even FDD port can be used as bidirectional GPIO.
