I am a 77 year old geek, who did NOT take typing in high school. However, when I started college in engineering I got a portable typewriter and the typing book that was used in the city schools at that time. I practiced some, but not enough to really think I could type. However, I was able to write reports and other papers using all ten fingers on more or less the right keys. I also had to keypunch my programs on two different model keypunch machines and for the PDP-8 lab we used what I think was an ASR 33 TTY for punching our ASCII tapes. This was all between 1965 and 1970
After graduation I enlisted in the Air Force and my first assignment during the Vietnam War was to punch the cards needed to update the data base on the system that monitored sensors along the Ho Chi Minh trail. This was a daily update just before dark and it HAD to be right. I punched and verified every card.
My next assignment found me using both keypunch machines and terminals for a Univac 1108/1110 computer and terminals connected to a DEC PDP-10. For each one of these the keyboards, other than the letter keys, were often very different.
In 1976, after service, I worked for an organization that had both dumb terminals connected to and IBM 360 system, more keypunch machines and a bit latter IBM 3270 green screen terminals for programming.
I was in that last job for several years before my boss even had a hint that I did not touch type. I could WRITE or COMPOSE on any keyboard with very little problems but the one skill I never learned, nor really ever needed, was the ability to transcribe from a document, either hand written or typed, using any of the multiple keyboards that I had to use regularly.
