"10 PRINT 'CLIVE'
20 GOTO 10

I typed 'RUN,' hit Enter, & watched as my name spilled down the screen in bright green-on-black text, over & over. For a 12-year-old in the pre-internet era? This was electrifying. I had typed a couple of commands—ones that seemed easily understandable—& the machine had obeyed. I felt like I’d just stolen fire from Zeus himself."
