It should be trivial to port this application to any other PIC micro-controller since they all share similar peripherals.

 First install [[:tools:gputils|gputils]] for gpasm and [[:projects:pickle|Pickle]] for ICSP (if you are using a Velleman K8048 for example). First install [[:tools:gputils|gputils]] for gpasm and [[:projects:pickle|Pickle]] for ICSP (if you are using a Velleman K8048 for example).
  
-Fetch the source and assemble the code.+PC Pointer needs some support files from [[:projects:pickle|Pickle]] so we install those first. 
 +<code> 
 +hg clone http://hg.kewl.org/pub/pickles 
 +cd pickles 
 +make 
 +make install 
 +cd .. 
 +</code> 
 + 
 +Now we can fetch PC Pointer and and assemble the code.

 +=== Usage ===
 +
 +Plug an old PS/2 mouse or newer USB mouse with PS/2 support into the input port of the circuit. Connect the serial output into the RS232 input of your old computer.
 +
 +Boot into DOS and detect the mouse with MOUSE.COM 8.20.
 +<code>
 +MOUSE.COM /C1
 +</code>
 +
 +Disable it like this.
 +<code>
 +MOUSE.COM OFF
 +</code>
 +
 +Windows 95 should auto-detect the device as a generic serial mouse.
