Amstrad Splitter Cable PCBs


Created on: 17-04-2019  By Gee
Ever since I realised that I could use 2 controllers or joysticks on the Amstrad CPC series, I had to try make some splitters.
A couple of weeks ago I drew up the schematics and then the PCB layout on CAD. Once I was happy with them I had the same company that produced my Controller PCBs make them.
Yesterday I took delivery of them and, they look great. Exactly what I was after, if not better!
Last night, when the little one was finally in bed, I set about soldering up the ports, diodes and the connecting cable that goes to the CPC. I soldered up one side and noticed that I was getting some odd results. The only button that was working when using the splitter was the fire 1 button. Then I found out that If I held down the fire 1 button, left would work. Also down and right were reversed. I'm assuming the diodes are the wrong way round as I've checked the PCBs over several times.
Anyway. I'm sure I'll figure it out soon! I'll turn the diodes round and see what happens.
