I recently came upon a Focus Electronics FK-6000 for extremely cheap. Now on to my questions. What switches does this thing have and does anyone know if the keys are removable on it? I have searched google, but I have found nothing about this keyboard even existing. It has a DIN adapter so I know it must be quite old and I would like to rehab it if possible. Judging by the other Focus boards I have found online I think it would have some kind of ALPS switches.
Thanks

Other Focus varieties (2001, 5001) seem to have white ALPS switches.
-
More likely than not - white complicated, clicky ALPS
-
Some later ones (the 9200 with trackball) have rubber dome+slider, but the caps are sometimes still double-shot and ALPS compatible.

According to this article: http://kbtalking.cool3c.com/article/8366
the FK-6000 is some sort of ALPS knockoff which the article calls a mantis-foot system (F4 on that chart). The Deskthority wiki says it could be a clone of the XM simplified ALPS switch http://deskthority.net/wiki/XM

Thanks for all the info guys!
How do I remove keycaps on these switches? If that is even possible. I really don't want to break this thing, but it needs a good cleaning.

I used to own and sell FK-6000's side-by-side with FK-2k's. The FK-6k comes in two flavors: genuine Alps White Simplified and Knockoff Alps White identical to the later FK-2001. That's pretty much all there is to it.
Also, AFAIK the Focus is not the XM, but another knockoff. I don't know exactly who made them. They feel different from the XM's though, especially the FK-2001's.

Use a keypuller. I only have wire ones, and they do fine.
Focus Electronic used an absurd number of different switches in their keyboards, in a Chicony-esque way. The original FK-2001 (which itself changed design) used blue complicated Alps, Type IV clones, some sort of clone alleged to be Omron, and apparently (and I don't have a reference for this) white complicated Alps (listed here: http://deskthority.net/wiki/Focus_FK-2001 (http://deskthority.net/wiki/Focus_FK-2001)). I'm not 100% sure that "Type IV" is one switch — I've got an NTC keyboard that's got something most the same, and that's what I posted to the Deskthority wiki, but it's not quite the same as what Alps.tw photographed as being in the FK-2001. Hard to differentiate manufacturing differences from clone jobs. I think I've nailed down what's an APC switch due to them having a reinforcement groove in the rear contact plate leg. APC is much easier though as their switches are still in production. So are XM switches, but no-one seems to have a photo of a confirmed XM switch disassembled (e.g. Filco Zero XM, Ducky 10**XM etc) and Xiang Min's spec doesn't go into enough detail.
I know the later version with Windows keys used Type III clones — I don't have a reference for those using anything else, but it would not surprise me.
(Focus's sales mailbox is still full and still bouncing mail!!)

Quite the informative thread this has been, and judging by this new board I would say that I don't particularly like Alps switches. I guess it's a personal preference thing, so I think I'm going to rehab this one some with a good cleaning and throw it up for sale. I have no clue what it's actually worth, but do people have a problem with DIN5 boards? Or do people just buy adapters to make it PS/2 and not worry?
-
Not really. Some people will go straight to a USB adapter.

It's more complicated than that. The ones on the board quite possibly are not genuine Alps Electric switches, but copies/clones. The various copies and clones do not have the best reputation when it comes to feel!
do people have a problem with DIN5 boards?
Depends. If the board is AT, or XT/AT switchable, you can just get a cheap adapter to put a PS/2 plug on the cable. I don't think this bothers anyone. PS/2 to USB is a much bigger headache, though.
If the board is XT, which this most likely will not be, that's when you need a converter, such as Soarer's.
