Err... Because the average field-servoid armed only with a flatblade
can't shift them :-). Of course more clueful people have a couple of
hundred different screwdrivers (as I've said before, Phillips != Pozidriv
!= JIS and Allen hex != Torx != Bristol Spline).
I've gone as far as epoxying a screw upside down onto the odd "security"
screws
way back when they started coming out and used a pliers/visegrips to turn the
rest of the screw and then either replace them with stock screws or clean the
epoxy off after reinserting them (if it was necessary to keep someone from
knowing that I was in there). Of course as many have pointed out virtually every
type bit is available in kits or separate pieces.Oh indeed.... But the sort of
people who go to those shops are clueful enough
The IBM manuals actively discourage you from
opening up the PSU. It's
held together by tamperproof Torx screws (you know, the ones with the
pins in the middle), and the Hardware Maintenance and Service manual
tells you to replace the PSU if these screws have been modified or
replaced with normal ones (i.e. if somebody has been inside the PSU).
I always
wonder how they can call it tamper-proof when you can go down to
the local hardware/car parts store and buy a set of them for maybe $5-10... not to put a nail in the fuseholder, or put unsafe
components in the
chopper circuit, or whatever.
Uh, penny under the blown screw in fuse, cigarette pack foil around the blown AGC
fuse. Let's do this right now.
