+== Control Cable Timing Issue ==
+It was been noted on [[http://www.midibox.org/forum/index.php/topic,13272.msg114171.html#msg114171|this forum article]] that errors can surface if the control cable between CORE and OPL3 boards is too long.
+  * The error shown in the forum article was found when running the testtone application.
+  * The specific error in the forum article that tone can be heard on outputs 1&2, but not outputs 3&4, however there is no guarantee that this is the only such error that could arise from long cable.
+  * The error was solved by shortening the control cable between CORE and OPLE3 boards. The cause was confirmed by switching back to a longer cable, at which point the error re-surfaced.
+  * The error was shown to be on the control cable (RS/A0/A1/WR), not the data cable (D0-D7), however it is advisable to make both these cables as short as is practicable.
