So to get a feel for Matias's Clicky switches, I got a Matias Tactile Pro 4 to play with. And because I wanted black keycaps and am a huge retro geek, I applied some keycaps I'd pulled off of an ancient Tandy laptop (80s era), which happened to be Alps-compatible!
The keys looked rather odd on my AEKII, but they seem to meld well with the Matias board, and get rid of the many excess notations on the keys, which I personally found ugly.
What do you think? Personally, I think it retros up the look significantly. Now if only I could get the case professionally painted in matte black...
(And, yes, that IS an Alps keycaps desk mat under it! Found that little gem on eBay.)
If anyone here is experienced at identifying rare Alps variants, I posted a thread about the keyboard I sourced these from:
