Next, I start to compare the values found in the above table with those found
by using moded on the various descriptors. What I find is that for all of the
descriptors _except_ for /t0, values for vector, pirority and port address
match.

Moded reports a vector of 60, priority of 5 and an address of $80002011 on
 /t0.

Further testing and playing uncovers another bit of weirdness. With a shell on
/t1 (and showing up in the IRQS table), any request of the floppy will lock up
the machine. Only a reboot will fix it. The same this _does not_ happen with
/t2. (I'm guessing this would rule out the 901 driver causing this problem
along with the my 'one-off' problem).

Looking at the IRQS table, I notice that the port address for /t1 is one byte
higher than the clock. I wonder if this is significant, given the gap between
other devices is at least 10.

Not knowing what the heck I'm talking about reduces me to just reporting what I
see. I hope it's helpful.

Ideas? Do I have an interupt problem or should I go looking elsewhere?

Steve
