The chart is here, with the cable corrected in chart B that I messed up before.
| = knit, - = purl. Where the row is blank, it means knit the knits and purl the purls.
Strangely enough, chart C looks like an upward-pointing chevron, but when worked it is actually a downward-pointing one. The symbols are written as they are worked, not as they appear from the right side.
The original pattern is here, and there is errata here.
