I am convinced that SKCM blue Alps and at least some SKCM orange Alps were factory lubed. I suspect that a dry lube such as molybdenum disulfide was used, but I have not tested this. XMIT has mentioned plans to do some testing.
Don't we have a couple chemists on here? I now Chyros does chemistry stuff, and I think I remember one of the other more well known dudes knowing chemistry pretty well. Is it just prohibitively expensive to scrape some lube off a factory lubed slider and toss it in some spectrometer, or is there really no way to identify these sorts of things other than testing reactions with other chemicals and using that to narrow down the possibilities over time?
Apparently it was some kind of industrial grade JIS lube.cumwagondeluxe wrote: Also, it seems like most people here feel like lubing alps (especially the older ones) ruins them - I'm really curious as to how some ~30 year old bits of dry lube could be so much better than anything similar we've got today. Would it really be so bad to toss some semi-scratchy SCKL green stems + tops I've got in a sonicator and then apply some e.g. dupont dry lube instead?

Relubing improved the switches but if the slider's were ok like the Greens I would of never done them. In the end they turned out much better than the Greens in terms of feel but binded a bit on off center key presses.
The other annoying part about them was that a bunch of the switchplates were bad so I had to scrounge replacements.

Recently, I returned two keyboards with SKCM blue Alps because of numerous unresponsive or chattering keys. I should have expected trouble, given the appearance of the boards. They showed signs of extensive wear and/or neglect. Sometimes dirty Alps switches can be restored by proper cleaning -- occasionally accompanied by careful lubing -- but this is not guaranteed, and you may end up having to replace some switches.
In contrast, I finally managed to acquire two Alps-switch keyboards that have no issues (except for not being SKCM blue).
One is a NIB Dell AT101W. Granted, the "Bigfoot" Dell has black Alps, arguably the worst Alps switch ever made, but the board is brand new and it works perfectly (within the parameters of black Alps switches). Moreover, it can be transformed into a Chyros-inspired "Clickfoot", either by clipping the tactile leaves or by swapping them out for click leaves from a clicky Alps switch. This is also the least-expensive Alps board I have ever bought -- it cost me $25.
The other is a Northgate Omnikey 101 in like-new condition. I am typing on it now. The case and caps are not yellowed, the plate is clean and devoid of corrosion spots, and all the keys work with no binding, no intermittent unresponsiveness, and no chattering. At first, I thought I had a bad switch under the PrintScreen key -- I had forgotten that the Northgate requires two keypresses to activate PrintScreen (I relearned this by consulting the manual that came with the keyboard). It also came with extra Ctrl and CapsLock keycaps for swapping these two keys as well as a thin plastic dust cover.
The dust cover that came with the Northgate caused some momentary panic when I was unpacking the keyboard, because the color of the transparent plastic is yellow-orange. At first I thought that the keyboard had yellowed more than any Northgate I had ever seen and that the seller had photoshopped the eBay images. Much to my relief, when the cover came off, the keyboard was the whitest Northgate I have seen to date.
It is great to experience Alps when they are in excellent to pristine condition!
NOS for sure maximizes one's chance to get Alps switches in good condition.Chyros wrote:Another convertHypersphere wrote: I think I might have finally learned my lesson, and I am going to try following Chyros' advice about holding out for Alps switches in excellent condition.

It is great to experience Alps when they are in excellent to pristine condition!. Everyone keeps underestimating how big the difference in performance is when it's NOS. The Acer and Apple IIc did very well at the UK keyboard meetups for that reason, too

My guess is that while the spring on it's own is light (iirc 40g? which would be relevant if you've removed the tactile leaf in an attempt to make SKCL Browns), the bump from the tactile leaf is large enough that in order to get past it you have to put in quite a bit of extra force.

Gotta love Reddit. What a totally disorganised mess. "Cherry ML - Mechanical leaf over membrane" — huh?
Tour please!Mattr567 wrote: So I got a great idea.
I put a SKCL Amber spring into a SKCM Brown, and the result is amazing. It's super heavy! You know how SKCM Brown kinda collapses after the tactile bump? Well imagine if it kept going! Lol, its a crazy switchUnusable for sure, at least for me. I'm sure someone could replicate this with SPRiT springs too.

To me, scrapping a beautiful NOS Alps keyboards to put its switches in some modern space-saving thing is supreme heresy. Of course, I can't stop them from doing it, but I've saved one or two boards from this terrible, unjust, undeserved fate.Menuhin wrote:NOS for sure maximizes one's chance to get Alps switches in good condition.Chyros wrote:Another convertHypersphere wrote: I think I might have finally learned my lesson, and I am going to try following Chyros' advice about holding out for Alps switches in excellent condition.

But is this a statement that encourage harvesters to harvest from NOS boards?
Not many people are flexible with adjusting to suit other keyboard layouts, and for those who can, they use external or internal convertors - this preserve the keyboards.
Majority just go for the caps or the switches, whenever the layout doesn't fit their habit, or whenever (99.9%) some tiny things are not their custom keyboard ideals.
Well, one (those who never bother to convert a keyboard) can say the existence of those terminal (e.g. Tandem) keyboards are meaningless and irrelevant today, and harvesting from them is arguably even better than normal recycling. But please make sure to spend some effort to understand a piece of history (perhaps the last piece of history from this computing / typing equipment) before harvesting and scrapping it.
