Last night I developed a roll of HIE in T-Max developer.  I had also
called the Kodak people.  I told them I had set the ASA at 320 and used
a #25 filter and I was told to use 5 minutes at 75 degrees with the
T-Max developer. I failed to ask about agitation, so I used a 10 second
agitation every minute, I was using a small drum.  The negatives looked
good, good contrast.  I haven't printed them yet, mostly likely over the
weekend or Monday night.
