I spoke too soon!
It got hung up and I had to reset; it took eight attempts to get it restarted.
I've called KB9EWG the unmercenary cyberhealer, and he'll be over Thursday or Friday (we both have doctor appointments tomorrow). He says I need a good dose of hard drive reformatting, and maybe a great long glug of operating system. Thiswill make me lose everything stowed in this little beige box. So, instead of blogging, I get to spend the next 48 hours or so putting all the box's data on floppy disks .......... oh what fuuuuuun, not.
Be back when I'm done with backup or poor computer is permanently healed.
