== Wireless Internal Version ==
Using the exact same circuit as above, I decided to create an internal wireless mouse for my 6128. The wireless PS/2 mouse receiver I've used is a Logitech C-RA1 seen here in it's original state, which can often be found for a reasonable price at your local flea-market or on your favourite online auction site, but any wireless PS/2 mouse and receiver should work.

The circuit remains the same, except for the fact that I didn't solder any sockets on to the PCB, but added fly-leads for the power, LED, PS/2 and Joystick port connections. I used flat cable for the joystick port connects, so that it can easily be routed below the CPCs mainboard. After removing the receiver circuit board from it's housing and removing the PS/2 lead, I connected the PS/2 wires directly from the receiver board to the adapter PCB and mounted the adapter PCB inverted on top of the receiver.

Unfortunately this particular model of wireless mouse has a relatively large receiver board, due to the receiver also having been used for the Logitech wireless mouse and keyboard combo. Despite this, there's room inside the 6128 to house everything, but you may notice I needed to relocate the earth strap from the mainboard to the drive bracket in order to make space. Alternative receivers might fit better however. The flat cable is routed below the mainboard and soldered directly to the contacts below the joystick port socket.

At the rear of the CPC I added a power switch for when I don't intend using the mouse. I took the required 5V from the lead going to the disc drive. Any of the two black wires is ground, the orange wire is 5V. To avoid drilling even more holes in the original housing, I used a 3mm LED filed down a little and wedged it between the cooling grill at the top edge. Then all that was left to do was put everything back together and my 6128 was fitted out with a wireless AMX compatible mouse.
