My goodie box arrived today:

Already opened, admittedly.

Lotsa switches!

The original packet was "officially" labelled, which gives us "proof" of SKCC series and SKCCAF:

Sadly no original Alps datasheets, packaging etc. Who did take the other three thousand, nine hundred and fifty, anyway?

I'm going to keep one left permanently disassembled, as they're a pain to disassemble and the side tabs are more than willing to fly off and hit you in the face:

I never did find where it went.

And lo, what's this …

Not what I was expecting:

Grey switchplate! This must be a later issue. There's also a ridge along the bottom of the base to hold the switchplate that seems to be a modification to the design.

Alps... just when you think you discovered all of a branch, it opens up new branches of evolution.

They chose the right name for themselves.

I seem to have the same switch as that used in the M0110A:

This figures, as the M0110A came after the introduction of SKCL.

I got about ten keyboards with this kind of switchs.

All tall cream Alps?

Per the wiki—[wiki]Alps SKCC Tall Cream[/wiki]—this switch is only known to have been used in the Apple M0110 and M0110A: do you have other keyboards with this switch?

Or are you referring to SKCC in general?

This is the oddest one:

The keyboard itself remains unidentified and sadly there isn't a photo of the PCB or controller IC to give us some idea of branding or manufacturing date.

SKCC itself had a clear overlap with SKCL; here's a 1985 one with the green switches:

That LED looks very tactile.

Great find!
:ugeek:

let me know if you want a keyboard designed for them.

I only have 50 and there's at least one person who wants to get his hands on them already.

You're not suggesting that you have spare keycaps for them, are you?

No, not at all.

One day, someone will make a keyboard that's exactly the same as my Poker II, but 75% …

I made a mistake. This is my KEYB.

Nice cherry-jade. Those look like green (and cream) Alps vintage tee mount. What keyboard are we looking at?

It's a good visual indication that green is lighter than cream, as cream is used for all the heavier and stabilised switches. The switches appear to all be the normal height.

What does the PCB ID say? It's clearly 12KC-something, maybe 12KC081O, but it's too small to read. I presume there's no code anywhere on the keyboard that begins "KFCC" or "KCC"?

He's already destroyed the ones he posted earlier, which are now 404. The keyboard is simply the one I posted earlier:

http://www7.ocn.ne.jp/~hisao/image/paso700.htm

However, MouseFan's example seems to have a different PCB code (12KC284A) but I no longer have the other images for comparison, also undermining the ability to use this topic as a visual reference point for green being lighter than cream. (MouseFan's page doesn't prove or disprove the use of cream switches, so he might have a different revision of the design with uniform switch weight.)

Oh well I guess cherry-jade does not feel like sharing then.

I'm sorry. It's late to report you,7BIT has post the adress of that keyb. Mine is exactly the same as his.

OK thanks for the link! 7bit owns the same keyboard? I did not know that.

There is a slight communication problem here but that's OK cherry-jade.

They're still hotlinked attachments from another forum — that's way too fragile for my liking.

Most definitely not! Apart from that I am just another user here with no admin role whatsoever as you well know. Anyway what I was trying to communicate is that cherry-jade is sharing little info's possibly due to a language barrier. But I do not know that for sure.
