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:

DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

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..

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.
