OK, thanks. Just once more then

That GPS is exactly what I described. That is not a PS/2 device it merely has a PS/2 style connector.  You carry a PC around with you for powering that thing? Didn't think so.

Just goes to show how short the straws are you are grasping for ...

Well it was my last word on the debate.  You can't honestly expect me to sit idle while you tell me what I possess.

The GPS has no screen of it's own, therefore requires a PC to use it, and gets it power from said PC through it's PS/2 port.

Sheesh, talk about short straws!

Actually, I know quite a lot about GPS (I gave a workshop and wrote several reviews on the subject) so I know what you are talking about and I know what I'm talking about. However, I really don't even need to know which specific GPS model you own since a GPS is never a PS/2 device. So, I could guess you have an Earthmate GPS receiver, but I could be wrong and that wouldn't matter.

Your GPS works perfectly fine with another power cable too. That you specifically ordered it with a cable that draws power from a PS/2 port doesn't make the GPS itself a PS/2 device. The fact that I can charge my mobile phone with a USB charger cable (or PS/2 charger cable for that matter) doesn't make the phone a USB (resp PS/2) device. Otherwise you could call all devices taking 5V at low power PS/2 devices.

In fact even that cable doesn't really need a PS/2port since that "PS/2" power cable could also be fed from a 5V power outlet with a female mini DIN connector too.

I have to say that the problem for me is not even so much that the example is incorrect, but more that I'm amazed you think this kind of far fetched examples will prove that PS/2 has to remain for a long time.

Call it incorrect if you want.  The plain fact is that it is that I told you quite plainly that it was only for power, and it would be a big deal for me if that power source wasn't there.  Of course I could always buy an adapter or a power supply, or heaven forbid,  batteries.  But these are all extra cost items/inconvenience items.

Now that you've beaten this small point to death, try something a little more challenging :)

Tailgunner:

Just jumping on the bandwagon of those that have PC joysticks that connect via the keyboard port. Saitek made a couple called PC Dash that connect via keyboard only, others (namely high end programmable flight controllers) connect to both a joystick port and keyboard port.

On the eminent demise of the PS/2 port, I'm reminded of a Mark Twain quote. ;) I'm sure they'll disappear eventually, but seeing as how stuff like mini-ITX motherboards include them I don't see it happening all that soon. I have noticed they've quit putting 5.25" floppy support in the BIOS of modern systems, and with the popularity of USB flash drives, I'd believe we'll loose floppy drives all together before we lose the ps/2 ports.

Nefesis:

ok, this is really off subject, buit from when Tailgunner said they'll porbably stop putting folppy drives in alltogether, i know i read somewhere (probably in the Maximum PC magazine) floppy drives will reemerge (altough they may be hidden inside the pc case) as they are needed for any type of RAID hard drives. not a problem for MAME machines, though, as i doubt most of us are going to use 250 gb hard drives. i could be wrong about this (the floppy drives, not the 250gb hard drives) and will recheck it.

The point is that it's a far fetched example (just like the other ones you gave actually). They don't even sell that GPS anymore. The new one supports ... well guess .... yep you got it ... USB!

Any way you put it, that GPS power cable is no reason for PC manufacturers to include PS/2 ports on PC's. They dropped ISA, and DIN keyboard connecters even though I still have lots of stuff for it collecting dust.

But I understand Tiger-Heli's explanation. Of course KeyWiz would loose customers if people would understand they will have trouble finding PS/2 connectors in the near future.
