Keeping you in my prayers, BigMike. You might want to talk to the youth pastor at your church. The young people are up to the minute on the latest technology and could probably help you with an inexpensive upgrade to your computer that would enable you to continue to use it. If you don't have any luck there, call the principal of your local high school. The STEM kids are a great bet too. The only issue might be that you would have to go to them vs them coming to you. School rules, you know...
Praying for you.
