Alps stabilizers on ISO layout


14 Apr 2019, 13:56

I need some help: what is the standard way to mount ISO enters with Alps stabilizers? If you have an Alps keyboard in ISO layout, you'd really help me out by lifting the keycap and take a picture of the stabilizer and the back of the keycap. Post in the comments. There probably are a few variations... I'd be really interested in a Matias keyboard.
I'm trying to make a switch plate for The Endgame Keyboard that works with Alps stabilizers. The space bar shall have holes for both Alps and Costar, the two unit keys are simple, but I can't figure the enter key out. Any help will be greatly appreciated! In the picture you can maybe spot the mounting holes for the enter stabilizers. Are they on the wrong side of the switch?

I was trying to take picture of the stabiliser on my Matias Tactile Pro in nordic ISO when - in true show of Matias ´quality´- one of the stabilisers came off. :D


After battling for 5 minutes with the slippery over-luber stabiliser, I manged to get it back in and get you a picture of it.

I had a (modified) Dell AT102W on the desk just now:

... because I was comparing it to the ISO AEKII. Not the Enter/Return key you want, but it has the same stabiliser.

Huh. The 0.25u narrower Apple key does fit the AT102W (with a gap) and vice versa (without the case top).
But the Matias and Dell keys are not compatible: although they are the same size and have the same type of stabiliser, the switch position is shifted 0.125u.

Besides Matias, Tai-Hao has also made Alps keycaps and Cherry MX/ISO keycaps, but I dunno about Alps/ISO keycaps.

Inserts for Costar-style keycap mounts (Cherry MX mounts), allowing you to mount a keycap with Cherry MX mount on the stabiliser to Alps snaps on the plate were shown in another thread recently.

Man, this is so useful!
I'm sorry I haven't seen this until today (will turn on notifications over mail or something). The topic is still very relevant.
To begin with, my orientation was inverted. I placed the supports on the other side of the switch. But that points to a solution: I can put supports on both sides of the switch. One to fit Alps and one to fit Matias.
It'll be necessary to supply a cap set that is guaranteed to work with this layout. Your suggestion to use a Costar solution is a good one. And if somebody wants to use Apple caps the problems won't end with the ISO. The shift is shorter, right? Fifth row mods are just... weird.
Food for thought. I'm very grateful for these pictures, and extra glad that you showed me more differences than I knew existed. Thank you!

I just saw this too, but it came up before during Blindassassin's Northgate PC board project. There aren't a lot of ISO Alps keyboards in the U.S. but I have managed to gather up a few examples. I started to document those, but apparently I'm still in the gathering (uh...hoarding) stage. From Blindassassin's research it turns out there are four Alps ISO Enter configurations. Three with a rotated switch (stem vertical) and one non-rotated (horizontal). Here's a link to that, and another where I posted a photo of the Focus version. You might have to scroll up or down just a bit.

I have examples of the following Alps-mount ISO Enter keyboards if it helps:

Focus FK-2002
Costar CSK-2102
Ortek MCK-84
Datacomp (Mac)
Azio Levetron
Acer 6312 (Italian)

First I think we need to come up with terminology to define the four different versions and a way to easily identify them.
