    I needed an adapter for my old clicky IBM keyboard to my new computer. No more ps2 connections on the new ones. Well, I researched a good bit and found that you need an adapter with the correct electronics built in to it to make them work together. The cheap $5 ones won't do it I plugged it up and the keyboard worked perfectly. I highly recommend paying a little more for this one to make sure that it works properly.

    Got a new computer, realized from pics on the site it had no ps/2 plug for my old keyboard (already using usb mouse). Either I needed an adapter or a new usb keyboard... Tried an old "direct" adapter I had lying around - as expected it did not work because it's more complicated than simply changing the plug (usb and ps/2 have different signalling requirements or some such). Tried a different brand model that looks similar to this one -- except the little square "box" in the middle on this Adesso is a fair bit larger, at least *implying* there is some kind of pc board inside it. The other adapter seemed to work and I was thrilled to be able to keep my ergonomic old keyboard -- but after a while the keyboard would suddenly just not *be* there, couldn't ctrl-alt-delete to get out or anything because *no* keyboard. Restart and it worked again - for a while, then quit again. Some searching around, and someone on a different site said this Adesso model was the ONLY one that worked properly for him because it apparently handles data correctly in both directions. Can't say *only* myself, but this time it works like a charm for me too! - no keyboard disappearing! (Installed driver itself on startup and then ALSO wanted to check with Microsoft "for better driver", hung up there and I told it to skip that - works perfectly ever since.) Thanks Adesso/Walmart! (Love the free site to store shipping, too!)

    The keyboards that come with new computers (even name brand) are cheap junk. I simply cannot use them. I love the feel of an IBM type big key spring action keyboard. But alas, mine is so old I already had an adapter on it to connect it to a PS/2 machine. And when my newest PC arrived, it only has USB connections. So, I looked for and found the Adesso adapter at Walmart online. With their no shipping pickup service and generous return policy, I figured I'd give it a try. It came in less time than I allowed and works exactly as advertised. I could not be more pleased (unless computer manufacturers send better keyboards with new machines!).
