Acorn RISC OS requires a mouse and it is very limited in use without it. This post describes in detail how to create a PS/2 Arduino adapter that connects to the 9-pin Mini DIN mouse port.

I was very fortunate to get this vintage computer from my friend Eric. This Acorn Archimedes A3010 was produced in 1992 by Acorn Computers and was based upon an ARM250 RISC microprocessor. Right away I proceeded to connect the computer to see if it still was in a working condition.

The bartop arcade cabinet is finished. The only thing that is left to do is to install the RetroPie system on the Raspberry Pi 3.

To finish up the cabinet we will place a marquee sign and connect the LEDs buttons on the control panel. In the end we will also add a protective plexiglass sheet in front of the screen.

It is time to close the opening on the back of our cabinet and add a cooling fan. A while back we cut out a panel that will function as the back door and predrilled some holes to attach the hinge. We can now finish that task.

As doctor Emmett Brown "Doc" in the movie Back To The Future stated: "Marty, I'm sorry, but the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning". Fortunately we will not need as much power for our arcade cabinet and a 12 Volt, 2.1 Ampere power supply will be more than enough.

An important aspect of gaming is sound. For that purpose we will need a set a good speakers and an amplifer that will connect directly to the Raspberry Pi audio.

T-modling gives the arcade cabinet that nice finish on the edges. I have chosen bright red that match the joysticks.

The most important and fun part of the arcade cabinet is the control panel. It consists of two joysticks and eight buttons per player. On the sides of the cabinet there are two additional pinball buttons.
