Apple //c internal drive instant fix.
Drive did not write: missing erase signal. Cause : faulty CA3146 (CA3086 equiv), that IC is nothing more than a container for 5 embedded npn transistors, but only one junction found broken.
Not so patient to wait for internet reorder, solution : Piggybacked with ordinary BC337 , WORKS !!! :-) Really proud of this 20 minutes repair lol
