Looking for an Ortek MCK-142 in working condition. Thanks

Not being an IBM guy, I have no use for all that,
but I do admire all the energy, care and precision you are unfolding here.

:D :D :D :D :D
That is not a bad influence....
That is what I call a solid plan for all to live by !!!

Hypothesis
I don't see it documented anywhere, but the shape of the actuator leaf is different in newer Alps. This is what is causing newer generations of alps switches to feel less refined. Before I go into more detail here, first some background:
Background
There are numerous well documented changes

No pressure, but my family has a habit of dying at age 60. And I turn 59 in a couple of weeks. So don't dilly-dally :)

I will probably try washers if I can find some small enough. Thanks for the tip!

Update: the M122 arrived today.
(Super big versions of the above photos: internals ; label .)
Looks like the date of manufacture was around September 25, 1985. Board needs a good cleaning and a screw/bolt mod, but overall it's a lot cleaner than I expected it to be.
I don't have a converter,

Hi @nfc or @nfc2, I am not able to find your listings on ebay and Wallapop do you mind share your contact details with me, I'm in for two pcb :)

Messaged!

Attempted a repair on a cracked barrel plate with ABS glue and it worked out better than I thought it would.
Put it on heavy with a Q-tip and let it cure for a week before I did a screw mod. I had a major break in the center
and hair line cracks running down each channel. This barrel plate is rare because

Switch bottoms have patina
Every switch was cleaned in the ultrasonic without mixing parts
1100 eur, eu proxy only
Can include 2x G80-0577 boards as bottom housing donors

Hi.
I'm a disgrace, to myself and to anyone who reads this. It turns out that—for some stupid reason—the date and clock were crossed. I think it's time to start wearing the glasses my wife gave me for my birthday.
Sorry :) Let's pretend nothing happened.
BTW (both boards are working as expected)

I'm looking for one of these...
( direct link to image )
...an OEM cable from a 1985-'86 IBM M122 keyboard (such as a cable from IBM keyboard part number 1389162), in new or good condition, not stretched out. Open to trades (I have a new-in-box black coiled IBM Model M cable, SDL-to-DIN5) or buying

Bump, still looking for this.

This is a very old thread, but I figured I'd add a data-point for foam and foil. I have a KB5151 that chatters (multiple of the same key output with one press) quite badly. It does this with most, though not all, switches.
And then a few of them just don't register every time, notably the shift keys.

Hi, I can not PM either.
Also sometimes i can not open this link here in China. We have a link in aliexpress too.
Could you contact us there and then we send a promotion code via ali message.

Hey folks, I'm working on restoring an Apple M0110 and found gerber files for a Pro Micro footprint PCB that works with these long stem alps. I spent a bunch of money to print a few of these on 1.6mm PCBs with thick ENIG surface finish - these feel really nice. I also spent some time to get the ZMK firmware

I found an old Motorola development terminal from 1982, and it also happens to feature the worst switches I have ever seen in a keyboard. :lol:
They are a linear spring-over-membrane design with a cross mount, and features an internal as well as an external coil spring.

Also a weird metal
