If I recall, it involves at least 41A of the drive microcode (I am running
424), and 2.19 of the library eprom (3575-L12/3575-L18).  I think it takes
the CE about 20-30 minutes to pop off the old chip, and pop on the new
one.  If you have 3570-C02/C12's (2 drives, 20 tapes), then I think it
only requires the drive microcode.
