Just some photos of the clock patch I made myself from the Phantom schematic, I *know* it isn't the prettiest but I was proud of myself
Schematic:
Backside of my pcb:
Front side of pcb:
Connection to DSP line:
Connection to SDMA line with capacitor to ground:
phantom bus accelerator & clock patch
Re: phantom bus accelerator & clock patch
Cool.
I actually found the capacitor made things worse.
Looks like the second chip does a inversion.. 40ns delay at 25mhz.. but with the delays of the chip, its probably more like a buffer..

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.

Re: phantom bus accelerator & clock patch
Also ctirad recommended for me to add these extra capacitors to my clock patch, but for some reason the Falcon wouldn't boot afterwards. Still, I took a photo for my records. I had to remove the capacitors afterwards. I think I remember him saying it was strange, apparently it should have just smoothed out the voltage a bit more.
