Peerless is curious — certainly a nice try. They have the distinction of being a true "quiet click" switch, with a click that is both clear and distinct but also very subtle. One disadvantage for me is the relatively long pretravel, just as with the Model M (FKB4700 seems directly based on the Model...

The identifying shot for SKCP is here: https://deskthority.net/photos-f62/canon-typewriter-keyboards-t4242.html Yours above look the same. It seems that there are versions without the plate retention clip bars, as shown in the photos on the SKCP wiki page. Maybe those are another series (like SKCO o...

I didn't get time to comment on this earlier. Let's take this photo again: https://deskthority.net/resources/image/45632 Look at the keycaps for C and V: the bottom of each keycap is level with the top surface of the keyboard. Now look at the expose switches, and where the scissor arms are when the ...

I just object to how it's impossible to resume a discussion that you stumble across by accident. Plus it's a chaotic and deliberately confusing mess of a site.

That, was not expecting. The really hard part will be convincing mainstream brands to sell laptops that are thicker, heavier and noisier! (Eyeball and ruler test of a Sunrex laptop keyboard gives me a thickness of around 4 mm without keycaps, versus 6.5 for X-Switch.) I've felt for a while now that,...

You're assuming that Alps were self-consistent at any point, or consistent year upon year. I only have one person's interpretation of the 1994 catalogue, as I've never been allowed to see most of it (whoever obtained it originally was denied permission to post it online). Also, companies can't decid...

More confusingly, "SK" stands for "single key switch" according to the 1994 catalogue according to Sandy, although I suspect Alps just made that up, or they just liked how it could be expanded in English. It's not "switch, keyboard" (there are SK-- parts that are not keyboard switches), but the keyb...

According to the specifications, KBM-01-01 is 3.5±0.8 oz (99±23 g), so that graph is just slightly outside the extent of the tolerance. MD-4P is cited the same, as 100±25 gf, and that's depicted as white-black-black, so the graph above is just slightly outside of tolerance in the other direction. As...

By the way, what happened to Press/Release for white-white?

Engicoder has a couple of types coming your way, NOS as I recall. That might help clear up some of the confusion.

By the way, MD-4PCS appears to be white/black/orange. I'm just using MD for the series, as that is what's in common between MD-4P (uncertain subset) and MD-7 (illuminated).

According to the Apple III service manual, the switches in the Apple III are "KCC" (momentary and alternate action) and "KFF" (double action). So now we have three naming formats for Alps series: Two-character: CL and CM, from alps.tw's photo and from the 1994 Alps catalogue Three-character: KCC and...

FWIW, the sliders (blue) and keycaps can be separated.

See under [wiki]Category:Deskthority media[/wiki].

That's the FCC ID, and KU6 is Super Gate Technology Co Ltd.

It's similar to [wiki]Monterey dome with slider[/wiki] but not the same.

It's at the point where a GUI table editor might be more practical :P

If I understand you correctly:

U → Greek upsilon: Υ υ
O → Greek omicron: Ο ο
N → Greek nu: Ν ν

No idea what the one in front of J is.

I will only believe that once we have reliable date evidence. So far it feels too close to the sort of believing-in-guesswork that has gone astray too many times before.

I'm curious whether these were ever used in products from anyone other than Olympia, or whether Olympia was their sole customer for keyboard switches. The intermediate type ("two-finger typewriter") seems to be a custom product for Olympia, from what Marquardt were saying — electric typewriters were...

Is this thing at all noteworthy? https://i.imgur.com/zJwWIaE.jpg It's certainly unusual. It appears to be either Maxi Switch foam and foil or Maxi Switch reed . The former is rare, and I don't know if the latter has been seen in a keyboard (neither type seems to be on the wiki at all, but I had thi...

Here's another one that it isn't :P

Thank you. Added.

Retouch the photos of them using Adobe, and write about them using Microsoft …

Check the serial number for the manufacturer identifier.

I am most fascinated by [wiki]ITT ETL18[/wiki]; I only managed to buy two, and HaaTa has one of those. Another company in the UK (Ellison Electronics) has a bunch in stock, but I still cannot get them to give me a price! I don't know if they're 20 p each or £200 each. I've never typed on them, but t...

the stem may look the same but I had these in the past and I could swear the acer caps were quite a bit thinner than the ortek ones. The pictures on the wiki don't look so different. However, I took the X keycap (and some other keycap that pinged off into oblivion) off my 6312 T1U/VI/UK from 1994, ...

An image for his keyboard is still very useful — we can never assume that any two keyboards are the same.

Is that mouse as unergonomic as it looks?

Nice job.

A close-up of the membranes would be nice, too (through one of the holes where there is no key) — you can see them in the existing pictures, but having a dedicated photo would be easy to pick out in the image gallery.

One of the PC Magazine keyboard reviews that I read (February 1992 or December 1989) mentioned the idea of capacitive membrane sensing, but said that no keyboards that they reviewed used it. Unfortunately they did not say which companies actually used it. The awkward part is not being able to see th...
