Also, code written in 1993 for that sort of machine would not be written to use acceleration. I think even OpenGL was only a glint in Khronos' eye back then.
In 1992, SGI led the creation of the OpenGL architectural review board (OpenGL ARB), the group of companies that would maintain and expand the OpenGL specification for years to come. On December 17, 1997, Microsoft and SGI initiated the Fahrenheit project, a joint effort with the goal of unifying the OpenGL and Direct3D interfaces (and adding a scene-graph API), and in 1998, Hewlett-Packard joined the project. On July 31, 2006, it was announced at SIGGRAPH that control of the OpenGL specification was being passed to the Khronos group.
One day in 1994, when I was putting gas/petrol in my car at the Shell station on North Shoreline Boulevard in Mountain View, which was the closest to Silicon Graphics' headquarters and other office buildings, I happened to notice the license plate on a yellow Ferrari being fueled by its driver on the other side of the pumps. It read "OpenGL", and when I looked at the driver, I realized it was none other than SGI founder and CEO Jim Clark. I guess it was his way of promoting OpenGL, although it is possible that some licensing fees had been paid to SGI to integrate with the proprietary precursor SGI Iris GL APIs, and that's where he "invested" his share of the fees.
Despite people confusing "open-source" with "free", this is an example of how one can make quite a nice living (and then some) developing and supporting open-source software and standards. Many people have no idea that virtually every standard used in our computing devices today produces at least a small amount of revenue from the sale of each device for its inventors/assignees, e.g., USB (Intel), Firewire (Apple), WiFi (Commonwealth Scientific and Industrial Research Organisation in Canberra, Australia), etc.
