I'm finally creating an account after perusing these forums for the past 10-12 years. I like to fix my own stuff so lots of great info here.
I have several computers and tend to hoard electronics. I need to organize them better but I do kind of know where everything is.
Let's see what else. Oh, I have custody of my 3 kiddos. They are 5, 8 and 10 years old. They take up most of my budget, hence why I fix things instead of replacing them.
My first computer was a Tandy 1000 TX back in 1990. This basically started my fascination with computers in general and I have always had a computer ever since.Comment
