Address (hex) 5000 : C396 System halted Since Greg and Steve are here to upgrade the lowl, I will not restart it. They will be shutting it down for modifications anyway. **PICS PROBLEM**: Tue Sep 19 16:36:11 GMT 2000 I will not start PICS this morning.

L00747 removed from drive #1. **PICS PROBLEM**: Tue Sep 19 18:23:47 GMT 2000 Occulting wheel motor's brushes and commutator is worn. Motor is quiet when it is horizontal, such as in the morning, and gets noisy as it becomes vertical, which is why it gets noisy later in the morning. We have not received the replacement motor from Greg. Greg will attempt to track its shipment as he says it was shipped a while back. Having no replacement, I will replace the noisy motor and we will run it until we get a replacement or it fails.
