I'm old enough to remember punch cards and being so excited to get an 80 column graphics card.
But all this talk of remembering back about building computers does remind me of the classic Monty Python skit about "back in our day" (which I am so guilty of).
Oh how times have changed. My kids equivalent to "when dinosaurs roamed..." is "the olden times like when phones were stuck to the wall."
Back on topic. For me, I really enjoy the discovery and tinkering of DIY.
