The question then is why IBM went to the expense of putting a fuse
connector inside the box. A wiretail fuse surely would be at least a
slight cost savings. I've never seen that fuse blown, personally.
My first 'PC Clone' was made with one of those old 63.5 watt IBM
supplies. In a totally non-matched Leading Edge Model D case. To fit
the supply in such a case, the supply circuit board had to be completely
removed from the steel case and just bolted inside the Model D case.
In the old-line IBM PC PSU's, there was always a big label on the
outside 'No user servicible parts inside' and a non-standard screw
sealing it. Every one that I've opened had a socketed fuse inside.
Sure.. And you'll find that if that fuse blows there are almost
certainly other component fialed as well (most likely the chopper
transistor or one of the mains rectifier diodes).
