Could I have used a Vector computer in school?

Back in school in the '80's, I had a computer/electronics class (where I first learned BASIC), and we had 3 computers. There was a VIC-20, a TRS-80, and one other that can't quite remember. I think it was an all-in-one type thing like the TRS-80 was, but I can't quite recall the name, except for the vague feeling that it might have began with a "V." Is it likely that a school would have a Vector Graphics computer in a classroom? If not, what's another likely option?

Just to clarify, "Vector" was what I thought the name of the computer might have been. It did not have vector graphics, or indeed any kind of graphics. Just text.
