... sinclair taught me how to touch type...
With the ZX81, if I recall, there was a serious supply/demand problem on launch.
My Dad had ordered one for us, as he was trying to get us into electronics - which was not difficult to do, because solder! Flashing lights! Beeping things! Radio!
It must've taken 3 months from placing the order to receiving it.
But the ZX Spectrum purchase was made at Radioshack, if I recall, after much begging and some heated discussion between my parents "All he ever does is sit in from of that computer!"
And indeed, I did. It got far worse with the Spectrum and my subscription to "Your Computer" monthly.
I learned to program basic, then started entering code from the "Your Computer" magazine, manually, painstakingly.
"It doesn't work", damn, check every single line of code again - "It still doesn't work."
Ok, I'll just start again from the beginning. "It still doesn't work."
In the following months magazine - an ENTIRE month, they would print code corrections.
To this day, due to the amount of time I spent typing - and the keyboard finger jujitsu that was required - I can touch type.
My typing speed is ridiculously fast - with zero formal training.
