Have you modded black alps before? I was thinking of doing something like using white alps click leaves with orange sliders.
I haven't yet modified any black Alps switches, but I have a NIB Dell AT101W with black Alps that I would like to modify one of these days. I was inspired to do this by Chyros' video in which he click-modded one of these Dell "bigfoot" boards, which he then dubbed ""The Clickfoot".

I and others have found that there is a major difference in bamboo (no slits) vs. pine (slits) Alps top switch housings, so provided the tops would fit on black Alps switches, when I get around to hybridizing them, I would want to include swapping out the black Alps tops with pine tops from, say, white or orange Alps.

Although I like the look of yellow or orange sliders, they are not visible when the caps are in place, and I am not sure they confer any advantage over white sliders. My crude measurements of slider friction indicated that the newer white sliders appear to be more slippery than sliders from older switches that apparently used some sort of dry lube, so new white sliders might have the advantage of not requiring any additional lubrication. However, there could be other subtle differences in construction of different generations of sliders. I need to break out the calipers and do some proper measurements, although dimensions alone will not reveal much about their potential effects of different sliders on, say, the sound or feel of the assembled switch.

I recently click-modded an AT101W, after using it linear-modded for a little while. Although I would still describe the experience as pretty mediocre, the switches still feel better clicky than stock tactile. The heightened tactility of the modded leaves mostly masks that unpleasant second bump that black Alps are well-known for.

I will also be getting one whose cable has been cut, but I am thinking of using the intact keyboard. If yours has an intact cable and if you can determine the pin assignments on the PCB header, please let me know. Thanks.
By the way the 6011 came today, but it didn't have a cable at all >_<

@//gainsborough: You might consider installing a panel-mount connector for a detachable cable. As soon as I can find the spare time, that it what I intend to do with my Acer 6011. I will probably also install an internal USB converter and do my customary HHKB-style remapping.

I ended up just harvesting the board - it didn't even have a case or anything, just PCB, mounting plate, and switches. What you're doing sounds interesting, though - I'm interested in hearing how that goes. Did you figure out the pin assignments, or do you even need to know that for what you're planning to do? I'm a total scrub when it comes to PCB tracing and converting.

@//gainsborough: The pin assignments on the PCB header should be as follows:

1. Clock
2. Data
3. Reset (possibly unused)
4. Ground
5. +5V

I believe this is the same for several Alps-switch boards, including:

Acer 6011
Leading Edge DC-2014; DC-3014
Zenith Z-150; ZB-2; 163-73

Oh cool. Is that the AT Z-150 or the XT? Or both? Are pin assignments and protocol mutually exclusive?

The Leading Edge needs the reset pin connected to PB7 on the Teensy.

@//gainsborough: I have the 100-1886 variant of the Z-150 (XT version). The 100-1860 variant is the AT version.

@fohat: Thanks for pointing out the need to connect the reset pin of the DC-2014 to P87 on the Teensy.

It is plainly visible in Soarer's documentation, but that is such a wall of TL;DR that it is often hard to tease out individual entries.

@fohat: Yep, the classic "hidden in plain sight" problem.
