I have an old Apple II. I got it years ago at an antique store, for much less than the seller could have asked. The only problem is that it was just the Apple II, without any disk drives, and no software. That means I could do absolutely nothing with it.
Eventually, some family members got me a (single) disk drive and a copy of Apple DOS for Christmas. I eagerly plugged it all up, only to have it go up in smoke. Turns out that when the power supply gets old enough, it can’t really handle the extra power draw from the floppy drive(s). I don’t think I’ll ever forget the sight of blue smoke (or the smell of it) coming from inside the box.
So now I have a broken Apple II. → Readlevania
