We were solid middle-middle class and didn't have a computer until 1989, and it was a "free", 2- or 3-year-old computer from my dad's work that they were going to throw away. We absolutely could not have afforded a computer during the 80s.
Even in the 90s, we kept relying on cast-offs from my dad's employer, and when I was preparing to go to college in '99, my parents scrounged to buy me the parts for a computer to build and take to college. But even then, my dad bought the parts at a discount through a former co-worker's consulting company, and vetoed a couple of my more expensive component choices.
And now that I think about it, my first laptop in 2003 was my dad's old work laptop that had been decommissioned.
You couldn’t afford a Commodore 64 or spectrum? Yet were middle class?
