The one I had was in perfect physical condition, didn't look yellowed at all, It also did end up in the EU so this could be it
Hi Jesseg, I got the chicony that doesn't present any yellowing, even though it isn't flawless. I discovered with my great disappoinment that the "end" key doesn't properly register, as you can see on the attached pic. I'll attach the serial number also so that you can tell me if this kind really comes from the other part of the world!
My regards.

@ dcopellino, I'd recommend that you desolder the End and Pause keys and flip them. I do use the pause key, but not often. You could also see if someone's willing to sell you a single switch and/or you could buy, say, an Alps orange switch and swap the switch plates.

The really bad thing would be is if you swap the End key with a known good switch and it still doesn't register.

Or, if you prefer a software approach, get a free copy of SharpKeys and map some other key to End.

Thank you for the right tip if I only were able to use the soldering tool :mrgreen:

Just bought the in worst condition IBM Thinkpad 700c ever. The rubber finish is a sticky mess and for everything that can be possibly broken, it is. The keyboard seems to be in quite decent condition though. Obviously I paid next to nothing for it. I see it as an amusement project.

I was curious about its keyboard quality, as this is the first Thinkpad laptop ever (1992) but haven't seen here any mentions or reviews for this particular model. If it finally doesn't end in the trash bin and it is of any interest, I will try to make a "review".

Hey, I only had limited soldering experience before coming here. I do recommend getting into it. Doing it is much easier than you think and there are lots of YouTube videos on the subject. Only real problem is that you do have to put down $80+ to get a decent soldering iron station and -- trust me on this -- a good solder sucker. (I also recommend flux pens, instead of wick or the cans.)

Just got this interesting piece. The seller (imo incorrectly by mistake) listed it as a Chicony KB-6926, but it's clearly an ACER keyboard.
KB-084C to be precise, a model which I found mentioned only once on DT in 2017.
The seller said:
"Can’t find another one like it. It will have come from a Philips/IBM research facility where my father worked so may have been a model that was on special order."
(and said it was untested, but I just did try and it works.)
I remember that Chyros mentioned in his review the KB-101A was the oldest ACER keyboard. Could this one be older?
edit: Clearly it's a (budget? silent/tactile?) version of this one:
wiki/Acer_KB-084AS
It has some kind of Mitsumi hybrid switch, but I'm not sure which variant it is yet. (PCB or membrane) I'll be opening it later in the week.
Also notice the stem hole is octagonal, not square as on other Mitsumi hybrid switches. The caps are not great, some kind of printed ABS.

Well, it's some kind of some with slider.

Possibly some variant of wiki/Acer_6510_series. The stem is octagonal, but the inner piece looks round.

Can you post a picture of a key removed from the keyboard? I'd like to see the shape of the stem.

I'll take pictures when I take it apart. But I do think it's a Mitsumi hybrid of some kind. The round outer ring in the photo is a rubber buckling sleeve. The key stem is quite small.

Two boards came in today...and from completely different worlds.
Bought the Model F because I had a Model M before that I really liked and people said the Model F was better feeling (the spacebar is heavy af though). The Cooler Master board has these "mem-chanical" switches that piqued my interest, but it wasn't that interesting otherwise.

BTC-5100C. This is after I ultrasoniced the keycaps.

The front legends for the "numeric keyboard" and Num Lock key are light blue.

It's a mini keyboard. The switches are BTC dome with slider. I also bought it on the advice of others. It's surprisingly nice. It's tactile with a very small click. The keys are dye-sublimed ABS. I'm very fond of the font. I can even use the "numeric keypad" properly. Only disadvantage, after typing appx one hour on it, is that the up arrow/page up is directly to the right of the shift key. Fortunately, I generally use the left shift key.

I think I'll put a Teensy in this and convert it to USB. I assume that this was a "travel" laptop, but it has a big ol' 5 pin DIN.

I doubt those are dyesubbed, as you can't dyesub ABS and reverse dyesub (everything but the legend gets dye) is very uncommon on vint boards.

Hmm. Interesting. So, if the keys aren't pad printed/silk screened, they're probably PBT? That'd be nice.

I doubt they are PBT, much less (reverse) dyesubs. Probably lasered, pad printed, or silkscreened ABS.
