This is a screen shot of my revised clock taken with the Hantek 6074BC.

Yes, you'll need a scope to properly adjust the CPU clock. On the CPU board, connect channel A to IC-Q pin 13 (phi 1) and channel B to IC-Q pin 5 (phi 2). Set the vertical scale to 1v/div and have the two signals at the same vertical position on the screen so they overlap each other. Set the time scale to see about one full cycle across the display. Post a clear screen shot of that.

Set the probes to the 10X setting and make sure the scope is also set to 10X on both channels, then set the input channels to10V or 5V per division.
It would also be good it we could see the graticule so we can determine of the timings are right.
