Program wouldn't recognize that the spare drive was hooked up as drive #1 (temporarily while regular drive #1 gets fixed), so it didn't write any data to that drive. I used the drive switch and display to define it as unit #1 but still data wasn't being written. Moved L00428 from drive #1 to drive #0. We will just use drive #0 for now and change the tape when it has 70 or more files on it.

MKIII COMMENT: Mon Nov 25 21:11:35 GMT 1996 Data look very noisy, lots of radial streaks. Wind from the West might have been blowing in a lot of dust, wind is now from the NE so maybe data will improve. CHIP COMMENT: Mon Nov 25 21:13:13 GMT 1996 Last hour and this hour the Display image doesn't look very good, as if I can't set a proper Display Gain. I thought it might have been caused by a bad calibration but after the last calibration it still looks weird.
