Prophet T8 and other s.c. keys with probs.

[Quinton Fulsom]

Almost anytime i've serviced a supposedly "dead" seq. circ. board or one
with erratic behaviors especially with memroy, it was remedied by reloading
a patch tape.  Definately try that 1st as it is most common remedy,
quickest fix in testing and less problematic.  I pretty much make it a
policy these days after beating my head on almost every one of their boards
to 1st replace the battery and then load a patch tape.  Hope that helps.
