It brings back memories for me of the first ‘real’ computer I had – a Kaypro 2x. That was in 1984, three years after the PC’s launch. Before that, I used a Tandy TRS-80 (cassette tapes!) and an IBM Selectric typewriter (golfballs!). And somewhere in my attic I have an Atari Portfolio (pocket computing!) which I bought in 1989.
Anyway, back to the Kaypro. It was running the CP/M operating system, still quite common at that time (aside memory: I first discovered WordStar at this time). Just look at the specs of that machine! My Nokia N70 phone has more computing power.
