A PS/2 style mouse is doable in hardware. One can fashion a small FPGA to do 
the PS/2 interface and then translate the position data to a voltage to feed into the 
Joystick port. 

Ideally the best solution would be to rewrite the RSBASIC code to handle both a 
PS/2 mouse and keyboard. Both would free up code space and improve 
performance of both the mouse and the keyboard.
