Hi, thanks very much.
I'll post a picture of the pcb, but I can assure you that it looks like new. I've checked traces with magnifier and I just retraced one thing that I found suspicious next to the DB15 ports, but there isn't the slightest trace of rust in this pcb. The PSU I am using works well with other Jaguars, so that shouldn't be a problem. I've tested all the Vcc on all the chips and all have their 5v+. Since it took a while to test, both Tom & Jerry got warm but not the kind of temperatures that could hint at a short (the DSP got warmer than the CPU, I hope that's normal). I noticed, though, that U35 was not outputting anything at pins 2,3,4,6,7,8,9,10,11 and others (the other Jaguar that I'm using as a reference outputs voltages around 2v in these pins). Does anyone know what these pins are? Or what the cause of these pins not outputting anything might be? I've taken a look at the schematics, but, apart from tracing circuits, I don't know much about what each signal is doing.
Thanks again
T
