I was hoping there wasn't an off-chance it was Simplified Type IV but rather Complicated.
Looking through the
ALPS switch wiki – indeed complicated and type I simplified look identical from the outside. Can't tell with type IV as there isn't a clear photo. Type II (XM) are obviously different in shape, and those are the rubbish ones that you want to avoid.
I seem to recall reading that opening up complicated ALPS is a bad thing as they're much harder to reassemble, so make sure you choose a worthless switch like scroll lock to inspect.
I don't think that any stigma should be attached to simplified ALPS in general – after all, they're our best hope of getting new and exciting boards produced, such as HHKB ALPS ... Oh look, a pig, up there in the sky ...
I set my Tactile Pro 3 up on my desk again earlier and after spending quality time with an Acer 6312, I was surprised how light and smooth the Type I switches were on the Tactile Pro 3. The tinny, pingy sound of Type I simplifieds is what bothers me more – but that may be more to do with the way Matias build keyboards, as I don't have a FILCO Zero Fukka for comparison (I would
LOVE a Fukka FILCO Zero 105, do you hear me Diatec??)
XM switches are the hated ones, as they're so stiff and difficult to type on, and you won't have those.
