- npsimons 13y agoIs it even that common to find hardware that will take a non-USB keyboard anymore? I've got some, but it's old.
- cjh_ 13y agoMany desktop machines still do, and most of the modern motherboards in full or mid-tower size still have a PS/2 port or two, for laptops PS/2 support is almost non-existent.
- jlgreco 13y agoI don't think that even thinkpad docking stations have PS/2 anymore. PS/2 support on modern laptops from non-obscure manufactures (leaving myself some wiggle room for whatever weird Chinese thing you might be able to buy on ebay) may very well be extinct.
- vetinari 13y agoThinkpad T430s: Standard PS/2 Keyboard. At least the device manager in Windows says so.
- jlgreco 13y agoThat's the built-in keyboard, right? I thought those were USB for some reason, I guess not. I guess it would be more accurate to say that PS/2 connectors proper (6-pin mini-DIN) are likely extinct in laptops.
- yuhong 13y agoI think it was only common for a mouse, and the PS/2 keyboard controller was only designed to allow one keyboard and one mouse, meaning that the laptops supporting this try to merge the two inputs into one, which is error-prone, particularly when dealing with for example wheel mouse when the packet size changes. Raymond Chen has a blog post, and there is a comment from Ray Trent (then of Synaptics) for more about the problems: http://blogs.msdn.com/b/oldnewthing/archive/2004/09/17/230839.aspx http://blogs.msdn.com/b/oldnewthing/archive/2004/09/17/23083...
- mjg59 13y agoLaptops are often still an approximation of PS/2.
- icelancer 13y agoAny/all motherboards serious about gaming with have a PS/2 port due to N-key rollover and interrupt-speed typing.
- yuhong 13y agoAlso due to fans of the old IBM Model M keyboards.
- Filligree 13y agoSo, uh.. what do you do if your system locks up at OS init?
