The current versions of ASCII Express and MouseTalk work on the IIGS.
If your versions support the ProModem 1200A then the odds are they
will work okay with in installed on a IIGS.

The Grappler+ card unfortunately causes problems with some IIGS software.
You would be better off getting a serial interface for your MX-80 or even
switching to an ImageWriter II, which is what most IIGS software supports.
However, software that already works with the Grappler+ should continue
to work on the IIGS.

The joystick should work.  The IIGS does have a DIP game port inside it.
