Proprietary keyboard connector?! The only place I've ever seen one of
those was a Packard Hell, where it has a special keyboard + mouse +
speaker/mic connector all in one. All the Compaq and HP machines I've
come across use plain old PS/2 (or sometimes USB) keyboards and mice.
Mind you, I pretty much only deal with their commercial line, so I
don't know what the deal is with the Presario systems.
Oops I just dated myself.... AGAIN! Way back, Compaq had a proprietary
keyboard connector - nothing else fit and there was no adapter - maybe
thats why people bought more than one?? I recall a Wyse 386 system we
got had a RJ-11 for the keyboard connector, just like their TTYs, but at
least they supplied an adapter with the system.
Of the HPaq commercial machines that I see (which is a direct
descendant of the old Compaq Deskpro/Evo line), they use all pretty
standard connectors except for the power connector. These are
definitely non-standard. Actually the new ones use one non-standard
connector for the main power but use the standard 4-pin secondary
ATX12V connector (or at least I think it's standard, though I haven't
checked the pin-out). It's not really such a big deal for these
systems though since they're mostly small form factor systems where
any other power supply just wouldn't physically fit in the case. In
the case of the few minitowers we've got, they normally use the exact
same motherboard as their corresponding SFF system, so they're kind of
stuck with the non-standard power connector.
A slightly more annoying problem with these machines is that a
standard floppy drive usually will not work. Fortunately floppies are
rarely used these days, but when they are needed, it's a bit of a PITA
to have to get a specific HPaq (or Dell) part at the rather exorbitant
prices they charge (~$40 US as I recall?)
So much for "industry standards" - makes DIY even more attractive.
