Description

Last time I measured the main clock the waveform was looking pretty bad. Need to investigate the issue.

The disc drive was still working so it might have just been poor probing.

I'm pretty sure that this is a probing issue when it comes to my specific oscilloscope/probe setup. So I'll need someone with a better oscilloscope to check it out. However it may still be a good idea to at least buffer the CD_CLK. Even though we don't need the fanout something like the PL133-37TC would work well. It's cheap and small, which is important since there isn't much room to squeeze in something for the CD_CLK.
