I had access to a DEC Alpha desktop workstation with a hardware OpenGL and X accelerator. It was in 1995, before the first 3dfx Voodoo was even released. I bet high-end Unix graphics workstations (CAD, video processing, etc) had it many years before that. The first graphics accelerator was offered by Silicon Graphics in 1983, yes, forty two years ago. It was supported by IRIX, a Unix variant.
