Hello all,

I just want to share my experience regarding a newly acquired Mac Plus. It was flup-flup-fluping when I bought it and to my surprise it had the Radius 16 accelerator! I uninstalled the Radius 16 and discovered that the Mac worked fine without it. After troubleshooting, I discovered that the +12v was being shorted to ground by the accelerator and after further troubleshooting I discovered that the 150uf capacitor was shorted and the rectifier diode (!N5822) was also shorted. After replacing these components the accelerator is working...See pictures...
