Any USB keyboard compatible with ThinkPad keyboards?

#1 Post by feklee » Wed Feb 27, 2013 1:07 pm

For a device that I consider building, I would like to use a ThinkPad keyboard, preferably that of the X4x series, or - if that's not possible - any other ThinkPad keyboard. Now, for connecting keyboard/TrackPoint, I need USB. So my idea is to use the electronics of one of the external keyboards offered by IBM/Lenovo to put between keyboard and the USB port:

Code: Select all

[keyboard from ThinkPad]-----[electronics from external USB keyboard]-----[USB port]
Is there any USB keyboard that I can use for that purpose? Any external USB keyboard that is compatible with the X/T/R4x series ThinkPads?

Why can't you use one of those external Ultranav keyboards that are designed to mimic the look and feel of the Thinkpad keyboard?
Current: X220 4291-4BG, T410 2537-R46, T60 1952-F76, T60 2007-QPG, T42 2373-F7G
Collectibles: T430s (IPS FHD + Classic Keyboard), X32 (IPS Screen)
Retired: X61 7673-V2V, A31p w/ Ultrabay Numpad
Past: Z61t 9440-A23, T60 2623-D3U, X32 2884-M5U

My idea is to use the electronics of one of those. In particular, I would like to use an X4x keyboard, since it is compact, and at the same time there are no Windows keys, giving way to comparatively large Alt and Ctrl keys.

More information about connecting ThinkPad keyboards by USB can be found in the thread "Could we kickstart fund a 4:3 machine".

I doubt you can use the electronics of an USB keyboard straight: if the keyboard matrix is even slightly different, the key mappings will be wrong. That said, it shouldn't be difficult to build a keyboard controller from any USB-enabled microcontroller. An arduino should do just fine.

That would be a great solution, though I would need to find an Arduino hacker, or give it a go myself.

If building a custom Arduino based controller I am worried, though, that it will be hard to support the TrackPoint.

find yourself a thinkpad USB ultranav keyboard in the "travel" flavor.   they're no longer made so be prepared to search.   once disassembled, the trackpad can be separated from the main keyboard, leaving you with a USB-driven keyboard without the winkey.

these keyboards were made by lite-on.   the layouts were identical with T4x keyboards but the socket used on the USB board is different than the T4x generation.



personally, i would recommend the newer version instead (despite the winkey, which is useful even in linux) since it's much easier to find and slightly less expensive.   unlike the version above, the controller board in this version can drive anything from a T60 to a T420 and even an X300/X301.   as long as it's a 7-row layout with a winkey and the proper socket, it will work.

I just bought one of the newer USB keyboards for my main desktop a few weeks back. I think it's the same keyboard as my X220i. I thought having pointstick would be advantageous with using two LCDs on my desktop. I knew there was a chance I would still prefer my current keyboard/mouse combo because of the 10-key and the center click on the mouse, but I have to say I didn't like it. For a $60 product, it felt a little bargain basement. The case was flexy, which gave a very different typing experience than my X220i, which is fantastic. Back to Amazon it went. I'm waiting for the wireless Bluetooth version of the X230 keyboard.

I have found them in shops in Germany, new, from 100 EUR upwards. That's a little steep for an experiment.

Very helpful information!
despite the winkey
I don't like the Windows key because it shrinks the size of the Alt key, which I use a lot. Under Windows, on my T41, I have mapped the Windows key to Caps Lock.

Actually, I prefer to use an X4x keyboard, because it's less wide than the full size T4x/R4x keyboards, and there is hope: In the German ThinkPad forum, we are discussing connecting an X4x keyboard using a custom controller, offered by CodeMercs. The TrackPoint is supposed to work out of the box, with PS/2 already coming out of the cable.
