My first IT job gave me one of those about 1992. It was a few years old, I was brought into the shop because I was a PC nut. The rest of the shop, and the facility, used dumb terminals on DEC-Net. It was kind of sluggish already by then. I used to bring in an AOL disk and download apps, copy them to a 3.5” disk and take them home. It was still just dialup, but I could do it non-my time.
