Glitch?

Many moons ago my Dad gave me a Commodore 64 to use. I used it for basic games but also to write simple command programs on, it was a fairly simple device but one that needed telling what to do. Computers these days are far more complex beasts as mine proved today, this I guess are the inner commands they need to function......or not. I have managed to save all of my images which is a relief and had to reset it back to factory defaults. That said I have a lot of installs to do.
New job starts tomorrow!!
