2 Filco 'board has a sort of simplified sw.
SIIG is supposed to have real alps. it doesn't have win keys, it has an AT plug.,,
these are usually a good sign for real ALPS ( not always). The seller is well know to k/b manias
as a guy who handles northgate omnikey and others with ALPS sw.
Seems like Miknitouch has real blue/click sw according to the review in Korean web site,
I often see Motery international( FKD) 'board with SMK-ish switches.
The reason of Yellow keys at function key line is that function keys are smaller than main keys.
2/3 sized versions were available only in YLW/GRN linear( no space for additional leaf spring inside the sw housing ).
don't know reason of white( or are they cream ) keys below function keys ( =, BS and a key
without printing according to pic in repair com )
If the price is reasonable, I'll go for SIIG.
