Two more chances to see shuttle/ISS tonight: 23:43 to 23:44 MDT. Low (max 11 degrees), due north 01:16 to 01:17 MDT. Low (max 15 degrees), NW to NNW And for the computer wizards out there: The ancient (circa 1999) Windows box I use to run my mount and cameras recently started forgetting what day/time it is after it's been powered down for a while. When I bring it back on line it usually thinks it's some time in December 1999. Shortly after that started happening I started getting a message on a DOS looking screen during boot up reading: CMOS checksum error - Defaults loaded Press F1 to continue, DEL to enter SETUP 10/15/2001-i440BX-<P3B-F> I press F1 and Windows loads. Then I set the clock and spend a night taking data. The clock seems to hold time fine all night. Any ideas? FWIW, I found a 20mm diameter, wafer shaped 3 volt lithium battery buried in the guts of the machine. Pulled it out and measured less than half a volt (ie. dead). Would installing a new battery cure the machine's ills? Thanks for any help, Patrick
