This is encouraging, though the Q800 and 840av tests are a shame. It occurs to me that I have a Q650 in which to test the RAM, just to make sure, and as it is essentially the same as a Q800, I need not go to too much bother to make certain of the A/UX situation.

I do have a Q605 and several LC475s, along with a closely-related machine, the LC575. When I get a few minutes, I will run some tests in these machines (and the Q650) and report back to fill this out a bit. Not any time too soon, mind you. Busy time and the machines are in some cases packed away.
