|    7m skew to phase0    |

      From: anthonypaulo@gmail.com              In the Apple IIe #2 tech notes for DMA, they state the following:              "...there will be some skew between edges of the 7 M clock and the timing       signals from the PAL, such as the edges of 0o or 01. This skew means the 7 M       clock edge may rise as much as 20 ns before, or 5 ns after, the 0o falling       edge. "       Is this skew only at the 0o falling edge? I ask because I'm using the 7m for       timing when to read/write.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
