Typing class.
7th or 8th grade...on manual typewriters, even though most of us had used electronic typewriters or computer keyboards by that age & the age & condition of the typewriters meant a lot of force was needed to move the keys.
The only thing I remember is the teacher instructing us: "a...a...a...space...semi...semi...semi...space"
When I got to college the classrooms had terminals hooked up to the school mainframe & I remember the foreign students pounding the h*** out of their keyboards, occasionally breaking them.
So I always presumed they learned to type on manual typewriters.
