Some friends and I decided that we would start designing our own hardware for our Apples //s.
We figured that we could make a better joystick. We couldnt find any specs for the ports, so we used a multi-meter. We found out that the joystick worked with resistance and that the closed Apple and Open Apple were also registered as joystick buttons. This new knowledge gave us the confidence to make larger leaps, like soldering our own cards up. We found Apple ][ shaped blank cards at a local electronics store. He also found some board level specs for us. Our Apple MLX codeing was shoddy and my soldering and math was worse! Moments after powering up our little card (an attempt at a simple analogue interface) the computer made a noise similar to R2D2 being fried. It also started to smoke.
The card was not happy, but the computer was none the worse for ware (less the greasy black soot that took forever to clean off). Like R2, it didnt seem to be phased. My parents never knew that I nearly destroyed the most expensive item in our home. Though they did toss the toaster after I explained that it was the source of the strange burning smell.
The guy at the electronics store was not surprised.
Neither was the teacher at the computer lab.
