I went to QCC from 98-01 and you'd sit in the admin building on an IBM green screen terminal and setup your schedule. There was little to no prerequisite checking so I made all sorts of goofy schedules and took classes out of order. I don't remember having any issues with it as the interface was pretty strait forward.

I wound up going back several years later when I was thinking of a different field and they had that trashcan CUNYfirst system. By then the UI was already outdated and clunky. I wound up with the wrong class the first time around because of some issue and have to have it changed post payment which was time consuming. I would have rather used the IBM's.
