Old layout IBM model M. In 1996, I got to clean out an elementary school's "IT department" as they were replacing everything, which included a couple dozen M keyboards made from '88 to '92. I spent some time refurbishing them and used them until 2020; never worrying about adapting to new key layouts.
(A skin condition causes me to shed hand skin prodigiously, I tried a logitech "fancy" $250 kb last year in between the old and new model M's; it lasted 3 months before keys stopped actuating)
