Sorry for the misunderstanding.  I am using Dr. Tanenbaum's code,
unmodified.  Although I didn't explicitly check it with a printf,
I believe it sets ps=1 for both the Model 50 & 60.  Dr. Tanenbaum
told me to add a line explicitly setting ps=1.  The code worked both
with and without that line.  I believe that in both cases, ps was 
set to one.  Is that more clear?

Please try the test I used, dd running in the background reading the hardisk
and the V1.3 tests running from floppy in the foreground.
