IBM KPD8923 Keyboard image gallery

Here is a bit of a blast from the past.  Back when IBM still made servers and PCs, they also sold rubber dome keyboards with integrated TrackPoint.  I got my little paws on an old, well used unit with some missing parts.  Never the less, it was useful for places that didn't have room for a mouse as TrackPoint is built-in.  Enjoy!

Further examination of the custom mod silent Topre keyboard


Yes, I am a fan of the new Ducky 104UB silent keyboard because it really doesn’t take away too much of that special Topre switch feel.  Yet, it still retain some silencing features that makes the board more appropriate for a quiet environment.  The Topre switch are fairly quiet to begin with when compares to the Chery MX blue for example.  So, it’s not starting out in a bad place per se.  The auditory feedback really is something else once somebody experience it.  However, I have been going back to reexamine the custom silent version that I had purchased sometimes ago.

Now, in my previous post, I noticed that the custom version probably took too much of that trademark sonic vibe from Topre switch, but also dampen the key to the point where it is almost flat.  I am back to check out what that flat means.  Topre switches are very smooth because it has very gentle slope going up or down the force-distance curve.  It’s just enough to let the user know that the key has been activated.  The arc has that beautiful s-curve that wasn’t too steep, unlike, say, a scissor switch.  I don’t have the proper instrument to demonstrate it, but the custom version has even flatter curve going by what I feel.

So, in a way, it’s almost like a linear switch because there’s no hills and valleys, except it is not linear, but a relatively flat line across all the distances.  The key force push back is as more or less constant across the distance.  This is different from a linear switch like Cherry MX red where the resistance builds up the further the key press goes.  So, it’s another way to look at why this particular mod makes it so smooth, perhaps almost too smooth for some folks because the unique Topre feel is gone.  On the other hand, this is such as smooth switch, it’s like pushing on butter.  This may have some folks salivating in more than one way.

My experience with this mod is that it is one of the quietest keyboard I have used with the most “flat” feel.  However, it’s not exactly a Topre switch anymore, but should almost be considered as entirely in a different class.  It just happen to build on a Topre switch and took great advantages of its unique design.

Reaction to Topre’s Realforce RGB announcement


At this time, most of the Internet’s focus is probably elsewhere by now that Computex has come and gone.  E3, Apple WWDC and a few other things like Legend of Zelda: Breath of the Wild are the talk of computer and video game folks.  So, I don’t want this one slip past me.

Now, just looking at the brochure, one of the first thing that jumps out is the LED lights are taking over Realforce.  So, I guess the 70s is back….  Another thing that is of great interest is the adjustable actuation distance, from the standard 2.2mm.  One can now select 3mm or even 1.5mm.  That is a cool feature that Topre switches can do easily, but difficult to say the least for a Cherry MX switch design.  One can make this change on the fly apparently.  So, this is probably either going through some sort of utility or press likely one of the extra keys on the upper right will do the trick.  I know that Topre has experimented with pressure sensitive switch; I am guessing that this is one way to put that coolness to good use.  Short travel keys are the rage these days….  However, then one is typing, a nice deep travel distance will decrease mistypes.

Also, Topre has changed the case design and the key caps too.  Because PBT doesn’t do transparent colors, I am guessing these are double shot ABS key caps.  I could be wrong tho.  The cap design also changed to a more flat shape Topre called step sculpture.  In any case, perhaps to cater to the more popular key cap shape than for the more recessed design that are more targeted to typist and developers.  One thing that is not covered by the PDF, but was uncovered by other blogs and commentators is that the keycap does not use the traditional Topre switch stem.  Instead, it uses Cherry MX stem.  Many folks have said that Topre just made Novatouch 104 RGB and that’s probably a good way to describe it.  This opens up a whole world of key cap options.  This should clear out a major weakness Topre suffered from.  On the other hand, Topre stems are very stable and sturdy and is a sound design for the intent and purpose.  Cherry MX key caps are pretty much industry standard now.  So, Topre will play along I guess if it wants to play in the gamer's market.

One more thing.  It appears that this is a uniform weight design, but it’s hard to tell from the brochure since it lists key weight as 45g+/-15g.  Topre likes to highlight the variable force aspect of the keyboard.  So, it would say so if that’s the case.  However, Topre lists the uniform key weight keyboard such as 104UG the same way.  So, I am going to go with consistency and put my bet on the uniform weighted side.  Besides, that’s probably cheaper to make…

Now, granted that all this is a prototype and Topre is just feeling out the market to see if there’s an interest from the gaming community.  They have some really cool technology sitting on the shelf waiting to be put to good use.  I think the biggest takeaway is the variable actuation distance.  There’s nothing in the market right now that is like it.  If Topre plays its card right, this could become the next standard keyboard at e-sports events.  Given how pricey it likely will be, I am going to say that this one is going to be an expansive toy.

New gaming keyboard from Topre? (Realforce RGB)

The folks from The Keyboard Company over the pond (UK) has spotted something very interesting coming out of Computex in Taiwan.  So far, I think they are the only one who has reported it.  (Nah, I am just late on the news, but they are the one with the PDF.)  I will let the annonucement flyer speak for itself.  Further analysis ahead about the new gaming keyboard from Topre, named ahem... Realforce RGB.  :)
