Here at Execucom we have a slightly different term for this 'device'. I
won't put it out on the net, however, since this probably isn't the place
to put adjectives regarding personal ancestory or public sexual habits.
Suffice it to say that if the person who designed the slide latch connector
were to come here and visit, his/her employer should only buy a one-way
ticket - we'd be able to ship what remains there were back in a shoebox!

Seriously, those things are a joke. When each and every part is made to exact
and perfect spec, they seem to work ok (at least until you touch them in
some fashion). The ones we got with at least 3 of our Suns and the cables
that we also got from Sun seem to be made to different specs entirely. We
had to do a good bit of reverse engineering to get them to handle the normal
vibration of someone merely walking in the office (concrete floors).

Junk em. Use screws.

Please, since you are protecting this 'Component Engineer', help him/her/it
:-) become aware of 'significant problems'.
