I can tell a scary story: I found hasro (year on case is 1991) and the switches are sucks. Small logo. Super scratchy. Cleaning not save.
I have another hasro, switches good (dirt/after clean same). Big logo, numbers on stems.
I have 93 Wyse-style terminal keeb. 26 switches with south cuts, battery smuf. Rest ones with north cuts, less smuf, but OK. All with small logo.
I have Cherry g80-1800 95' switches OK. Big logo.
