The good news is that my computer doesn't seem to be completely fried. It's just partially fried. No internet - that seems to be out of commission, and a bunch of keys seem to not be working properly, but I've now got my photographs and more importantly my knitting patterns backed up to jump drives, which is at least a start.
So, the okay news is that I've at least got some limited use of a computer. The good news is that I can put off having to come up with $800 for a new one for a month or two at least, which is good because Rhinebeck is coming and all my extra money is getting put away for that right now.
Must keep the priorities straight.
