This caused some problems, the animations display didn't work, the data scan files are named incorrectly. I exited and cycled the main power switch and restarted everything for the MKIII. That fixed the problems. I will delete the misnamed files, there are only 20 minutes worth.

I exited the program while the mirror drive was off, so it can cool down.

I pulled it out and am letting it cool down before I observe. **PSPT PROBLEM**: Wed Sep 16 20:30:44 GMT 1998 I installed the driver board and used Run to start observing.

They are still functioning but how well they cool is dubious since the rack is only vented at the top with no cool air inlets down low. But the mirror drive module didn't get very hot so maybe it only gets hot after something causes the mirror oscillation to take place. Haosheng is sending out a spare mirror driver board for us to try. By the way, pull out a few of the bigger modules in the lowest section of the cabinet to be able to see the fans from the front of the cabinet.
