I'm trying to fix a problem with an RL01 drive;
the drive spins up to speed OK (the scope shows that
sector pulse is within required limits), but
the fault light comes on before the heads move.
The FMPS available at www.mainecoon.com covers
version 1 of the Drive Logic Module, however
I have version 2 (part 54-13531) and the circuit
layout is quite different.
Does anyone have a copy of the FMPS for version 2?
I need to know what causes pin 11 of the 74279
at location E6 to go low. Hopefully the printset
has a comment explaining what this latch does.
I have a second drive working OK on the same controller,
so I believe the controller is OK.
Thanks in advance.
Francis
