My family always described what I was doing with my C64 as &quot;playing with the computer&quot;. Sure, I played games on it, but I also spent a lot of time typing in those programs from the magazines. Younger developers today are shocked and amazed when I describe the hex dumps with line-by-line checksums they used to print, and that your first challenge was to type in the code-entry program mistake free, without relying on the checksums to get every character correct.<p>To this day, even though I touch-type most of the time, I can still type quickly with one hand, while the other hand is used to keep my place on a printed document I&#x27;m transcribing. (Not that I do that much anymore.)
