Heh! Oh the memories! I got my great grandmother's Underwood (1890s) when I was 10. QWERTY layout. Taught myself touch typing on that monster built like a tank.... though it took about 6 months to get up to about 30wpm (that dang hard to use).
About age 12 riding bikes with my younger brother, we passed a pile of rubbish set out on the curb and in that was a 1950s Royal, Pica 10, Standard platen. Balanced the beast on my bicycle seat and managed to get it home. It was in pretty good shape, excepting two bent keys that Dad managed to straighten out with pliers and elbow grease. I was the only kid in elementary school who turned in typewritten class homework assignments. That caused a problem as one teacher said my parents were doing the work. Mom and I arrived at the school one afternoon and demanded that I be given a chance to show my skills on one of their office machines. After that no more problems. :)
Collected another Royal office machine, this time in Elite 12pica with an extended platen (12" wide) which remained my main machine for 15 or so years.
In the 1970s I started with IBM electrics (Selectric 1, Selectric II and finally 3 Selectric III) with font balls numbering about 20, both normal and italic.
Did some reporting for local newspapers on a niche market (music/live shows) and timely product, readable and precise output followed. For a period of time I fancied myself a "novelist" and really began banging out the words per minute (I CAN type as fast as I think, but my fingers do not alwyas (example error) keep up.
1980s (early) I got a PC. Had an IBM keyboard with the Selectric touch that cost nearly as much as the computer itself. Lasted me about 18 years before upgrades, etc, made it impossible to connect to the new hardware (dongles were not generally found at that time). Tried a bunch of the rubber and sponge cheapo keyboards, liked none of them, and have always invested in mechanical switch keyboards ever since. Some can be found as low as US $40 with smart response and that "clickety sound" that tells you you bottomed out the keystroke!
Have you always typed that fast? Or did you make progress over the years? How much faster do you type using mechanical keyboards? Just wondering.
Everything gets better with practice. Touch typing is thinking in WORDS not letters. My speed on sponge and mechanical keyboards is about the same, but the sponge keyboards is not RESPONSIVE and a lot of letters are left out. Sigh!
HAVING SAID ALL THE ABOVE: Speed kills, everyone says so. Find the right pace, the stamina for the long haul, and above all, learn two handed touch typing. Learn to think in WORDS not letters. Practice TRANSCRIBING (keeping your eyes on text from another source and NOT looking at your output (screen or paper). Gain confidence in the keyboard and the rewards down the line will be immense, particularly if you are coding!
I've been keyboard wise for nearly 62 years. Just got a head start on most folks.
In the final analysis it is not how FAST, but how ACCURATE!
