I did essentially the same thing, although I modified a 1006V-MM1 for the 
alternate interrupt and address.  I tried it with a Seagate 4051 (40 meg drive)
and had the identical problem.  I think that there is something in the
controller card (my guess only) that may be dying.  I did notice that
when the system died the drive hooked up to the second card was
permenantly selected (I had the drive led on the computer hooked up to
the second controller card, and it went on and stayed on.)  My feeling
is that this seemed to occur during periods of heavy io.


If the Adaptec card works could you let me know?
