 This is a very simple PS/2 to serial mouse protocol converter which uses
-a PIC micro-controller and MAX232.
+a PIC micro-controller and a MAX232.
 === Schematics ===
-{{:projects:pic16f628a.png?200}}
+Two schematics are presented for two different PIC micros. It should be trivial to port this application to any other PIC micro-controller since they all share similar peripherals.

 {{:projects:pic16f688.png?200}}
+=== Install ===
+First install [[:tools:gputils|gputils]] for gpasm and [[:projects:pickle|Pickle]] for ICSP (if you are using a Velleman K8048 for example).
+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.
+<code>
+hg clone http://hg.kewl.org/pub/PCPointer
+cd PCPointer
+make
+</code>
+The resultant hex file is used to program the chip. Here I use [[:projects:pickle|Pickle]] and I have targeted the 16f688.
+<code>
+p14 program pic16f688.hex
+</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.
