You could be thinking of “personal computer with Internet access”? That’s closer timing as long as you want something more open / capable than the various dialup services which were popular with personal computer users starting in the 1980s.
I started college in 1982, majoring in math and physics. The professors all had personal computers on their desks. I bought myself one for under $1000 the next year. By the time I graduated, even the computer science professors were using personal computers, though student assignments were still done on the mainframe.
I did some searching. Most stats suggest that by 1985, more than 10% of American households, and a slight majority of small businesses, had a personal computer.
By 2001, it's 60% and nearly 100%. I agree with the others. You're about two decades too late in your estimate.
In San Diego, in 1987, I attended college using Pell grants from the US government because my family was considered below the poverty line. They provided enough money to cover tuition, books, and room and board, but I lived at home and used the room-and-board money to buy an IBM PC AT clone.
This was not my first personal computer, but it was the first that literally has "Personal Computer" in the name, and is more than ten years prior to your claim.
