Hi Bill,

Thanks for the enlightenment and edification! The computer I was
referencing is a dinosaur by today's standards, 266Mhz 4GB HD. I have
done a little tweaking by adding more RAM, second HD, etc. all of
which I had from previous 'donations'. All told the machine has only
cost me some frustration and exercise in patience. It actually serves
my purpose quite well in running Guide 8 and controlling my LX200GPS.
I have much newer machines but this'n has a special place. ;^)

Clear, Dark Skies!

Dave
