An overclock from 16.67MHz to 25MHz, .8 sounds about right.  Great job and write-up, bonus points for saving the floppy drive!  :)

Haha! I'm loosing it lol. It's 12 and -12 isn't it? I run a 12v fan with a similar cable.


I haven't measured in a while but pretty sure floppy connector is +12V-ground-ground-+5V. I run the fan in my A500 off that at 5V so it'll be quieter. I don't need it to move a whole cyclone worth of air, lol. ;)
